Official Samsung Epic 4G Touch D710 car mount review

I just received and installed the official Samsung car mount. Physically, it has incredible build quality. Both the suction piece and the actual arm look and feel as if they were designed to withstand people trying to break it. The aesthetics are also top notch. Performance is what I was looking for. I no longer have to plug in my headphone jack into my phone every time I get in the car. I can now pop my phone in and leave Pandora running with the screen on without worrying about being distracted when changing songs or draining battery life. The adjustments available are perfect for me since I mounted mines on the windshield. If you want to mount it somewhere else using the plastic dash piece they give you, the fixed arm and adjustable joint may not provide you with as much mobility as you'd need--depending on where you mount it.
This dock is easily worth the $36 I paid for it, that much I know for certain. I have a similar dock from when I had my iPhone 3GS and it looks flimsy and cheap compared to the Samsung mount even though both cost approximately the same. For the price, the dock and charger combo are hard to beat. It's also a lot more convenient to use than a dock that doesn't have the phone connections built in.
All in all, I'm incredibly satisfied with the purchase.
In case you're wondering how it hooks up, here's a youtube link for the T-mobile Galaxy S2 that another user posted. The Sprint version is exactly the same, except for adjustments made to the flexible plastic to fit our phone.

No problem. Be sure to note that it may not fit your phone if you use a case. I haven't pushed the charger yet to see how much of a load it can handle before the energy use by the phone outpaces the power supplied by the charger. Thus far, I've only run Pandora with the screen on a 100% of the time and it still charged the phone a good amount. I'm hoping I eventually get the chance to test out google maps or navigation with pandora running to see how the charger holds up against that type of drain.

i have this, very happy with it so far.

Question: How does the phone know it's docked to activate Car Mode? Is there a magnet in the dock that the phone picks up on like the old DROIDs?

Based on this review, I've ordered one of the mounts for myself. I'll report back when it comes in!

I believe it detects a certain resistance or short across a couple of the USB pins.

Who's Interested in a Auto Dock?

I'm designing a dock for the N7v2 for use in a car. It will have Qi wireless charging and Bluetooth audio receiver, with a standard 3.5mm audio output. It should be compatible with most cases.
I am also currently designing a mounting method that should be close to universal between different cars, and should not fall off like most other docks in the market.
I designed one for the N7v1 using the Pogo pins, and I can never go back to not having a dock for my tablet in my car. It's amazing the difference it made for me.
I want to know a couple things.Please reply with the following template:
1. Would you want a dock like this?
2. How much do you expect to pay for it?
Thank you everyone, in advance!

Sounds like a great idea. Do you have any links showing your work with N7v1? Heck, I may be interested in that version since the v1 tablet can be had for cheap these days and is more than capable for the limited functions needed in a car. At any rate:
1. yes, would be interested
2. no idea what a fair price would be, but $50-$100 seems like a fair ballpark

I would think very carefully why you need a wireless charger in a car.
Heat kills batteries; tablets in cars get hot. Why add heat to your woes?
The tablet is likely to be busy playing music and navigating, often in full sunlight. Why add to the heating problems by using a wireless charger when a 5v cord charger attached to the car supply will do the trick?
The wireless car mount/charger iterations for the Nexus 4 were a failure, I recall.

I've attached 4 pictures of the dock I made for the first Nexus 7. You'll notice that it inst exactly a dock you can put in just any car. I realized I made a little too rugged... and big!

Well, that's why I don't leave the tablet in the car, I keep it with me. While I'm in the car, if it's hot out I will have the A/C on anyways, so heat has not been an issue.
Most of my broken devices are dead because the USB port broke because of wear and tear. One of the points of this dock is to reduce that. Plugging in a device everytime I get in the car is partly to blame for such failures. I would have used Pogo Pins, like with the first Nexus 7, but they don't exist on the second.

Shared app developing ideas
Hey everyone,
my name is joseph and i am new to this website. I am also new to the whole rooting phones as well as i am learning the basics of computer science-- os, rom, ram, eprom, android, custom roms.....etc.
I honestly have no idea what i am looking to read and study up on so if you have any ideas than please let me know so i can educate myself. I end goal is to be a program developer.
Also i have an amazing ideas of a great new app. I have the layouts for the app but don't have the knowledge to build the app myself. If you are interested in learning more about my idea and possibly collaberate pleae let me know and we can possibly exchange numbers.
Another thing, i am an inventor and creator.

Look at active Brodit car mounts - say for a Nexus 4. There the device is supported and aligned as it glides onto or off the USB. There is no possibility of twisting or yawing.
I think your proposal maybe over-kill - simplest solutions are always best IMHO. A guy in the Nexus 4 forum came to no good end and had a lot of unhappy 'subscribers'. Just saying.

I would normally agree. I was hoping to make one that doesnt require a case to be removed to use. I designed my previous dock the way you describe (except it used the Pogo pins on the side), but I always had to remove the case and eventually the first case was showing signs of damage from being removed so often.
My hope is that the base platform of the dock I want to build will be compatible with multiple models of smartphones and tablets that are Qi capable. That'll require a lot more planning, but may be worth it.

Well if you're set on the route you've described; ... I see you've picked up on the Peltier pump in another thread. Credit me somewhere if you make it!
But I might consider an approach made by Philips in an Android Bluetooth Speaker and dock. The adjustment for USB and its placement on an edge, plus 180 degree rotation needed for some models, was catered for physically. A much cheaper approach which copes with tablets and phones!

I think I will use a Peltier pump. And yes, I'll make sure you get credit for that idea I'll mount the transmitting coil onto the cold side (probably with a layer of copper in between, we'll try several things) and have the hot side of the pump mounted to the aluminum/sheet metal of the back plate (probably with thermal paste as well). I'll have the pump on a simple thermostat. Good thing I have an EE helping me with this project
Hopefully the final product won't need a Peltier pump, but I will definitely have it in the prototype.

I haven't had very good experiences with using that type of dock The results of daily use tend to be USB ports that are stretched and loose. At least that's how it has been in my experience.

Don't forget to talk to your EE about eddy current loses in any conductors (copper, aluminium) you have nearby to your induction coil.

Interesting read, but with the cooler this is going to be a very expensive dock. Without it, look to Canada for your market.
I rigged up one for my Nexus 4 last Winter. Based on some testing, I used the most efficient charger I could find for that phone (the LG wcp-700). It worked very well... until late spring when the mercury broke 70. To make a long story short, I pulled it last month as the phone was getting too hot. This in a suv with a 4 liter v6 with plenty of air conditioning, front and rear.
Without the cooler, the tablet needs to be located directly in front of a vent, or even in moderate climates the unit will get hot enough to significantly reduce charging current.
One more thing to consider... the Nexus 7 is polarized vertically. This means that it is invisible in landscape orientation for anyone wearing polarized driving glasses, which I am willing to bet is a large percentage of your prospective market (tech savvy, auto enthusiasts). Most displays designed for vehicles are polarized at 45°, making this not such an issue.
While the tinkerer, software developer, and electronic geek in me wanted a fully integrated tablet in my truck, I soon came to the conclusion that it was simply not practical. What is really needed is a properly done appRadio, where a head unit can mirror the display of a mobile device (ideally wirelessly - miracast, etc.) with a control link set up to pass touches on the head unit back to the mobile device. We're about 30% there now, but a lack of standards, and major players wanting proprietary solutions is a problem.
I wish you much success with your endeavor, but just wanted to share my experience and feelings that this will not be all that marketable a product.

The problems you had with the nexus 4 does not necessarily effect the nexus 7. The nexus 4 was pretty terrible at wireless charging. I had a car setup with a qi charger with the lumia 920 and it worked great even in hot weather. I am not saying the nexus 7 will work, but it might.

What makes you say that? I ask as I have seen relatively similar performance with both the N7 and N4. The tricky thing about the N4 is that the coil is not centered in the vertical dimension, so for folks making the assumption that it is, there will be quite a bit of offset.

I say that because of all the issues people had with car docks. It also had issues with the dt-900 qi chargers when it shouldn't have. It heated up excessively with most chargers.

I wonder if there will be an Official dock that lets you:
1. Charge
2. Expand TV HDMI out
3. USB port for Hard drive access
I really want the Nexus & FHD to be a Home entertainment player...may be a remote/ Or Kinect like gesture control app built in with the dock
Hope this comes true...it will be the best Combo for a home unit!

Docking Station

Hi,
so soon my nexus will be here and after over 6 years with iPhone I'm moving to try android.
one think i always loved about my iphone is the docking station, makes life better and easier.
now with the iphone its very easy to find docking station that fit 100% right, and then i dont have to worry about damage to the charging port, the phone is held up very tight and i never had any problem.
on the android camp its harder to find phone specific accessories so heres what i manage to find:
im looking for a cheap solution but can pay a little more if its really worth it
cheap:
http://www.ebay.com/itm/Micro-USB-D...AU_MobilePhoneAccessories&hash=item2ecab22c6d
expensive:
http://www.ebay.com/itm/Universal-M...Phone_PDA_Cables_Adapters&hash=item43c158ab0c
the expensive one at least comes with a cable, and heres a video i found that shows that this product might be a better choice:
http://www.youtube.com/watch?v=wTyGmNTh6iA
i just dont want the device to wobble freely hanging only by the usb connector.
i also hear that micro usb is much weaker then apple connectors so im a bit worried.
any1 have any experince with such products? what do u think? am i risking damage to my usb port? thanks.

IMHO ... yes, you are risking damaging the port. I personally wouldn't even consider using one as I've gone through a bunch of phones that the Micro-USB eventually stopped working properly. The Nexus one was notorious for that problem as have been quite a few other devices. Micro-USB just doesn't hold up over time.
Now, back to your problem. One thing the Nexus 5 has over the iPhone is Qi Wireless charging. So, might I suggest stop thinking in terms of how you would plugin in your iPhone to charge it, and to sync it with iTunes. All of this can be done using apps that sync wirelessly (iSyncr etc) and a good Qi charger.
Here's a good starting point for a "dock" like standing position while your N5 charges:
http://www.amazon.com/Nokia-DT910-Wireless-Charging-Stand/dp/B00A3NCC8M

It's important for you to note the orientation of the Micro USB port on the phone. On nexus devices reversed compared to the samsung phones those docks are for. I own the dock on the first link. It will not work with the Nexus.
You need one that's pin-side facing you. Unless you want the phone facing away from you
It's an annoying aspect of the Micro USB standard -- when it comes to direction, there is no standard.
DIY: Not ideal because it doesn't LOOK great but does WORK great. I bought the dock from that first link for my S3 and because of its 'universal'ness it was extremely wobbly, putting much undue strain on the port. I stuck a couple wads of Sugru down on the dock and behind the connector (where the phones back would rest) and stuck my phone in. When it dried after 30 minutes I had a perfect custom fit. Looked like **** though. Function over form in this case.

this...
but this is also a relatively new thing as the Nexus 4 was the "standard" way that everyone is used to (small side up where the Nexus 5 flipped it to small side down)

For charging, I would recomend the Google's wireless charger: https://play.google.com/store/devices/details/Nexus_Wireless_Charger?id=nexus_wireless_charger. As for syncing, what kind of things are you going to sync from your computer to your phone? On the android side the majority of things can/are synced over wifi or cloud services.

Thanks for all the answers...
I didn't think about orientation lol, i forgot about this issue.. so docking stations seems meh ATM
about wireless chargers... quite expensive IMO and i always fear that since the phone is not being held tightly it might fall and break.
i put my phone on a nightstand near my bed so accidents in the dark could happen, and i also like it when the phone is standing so i can see the screen without picking it up.
so that limits the range of wireless chargers i can use.
syncing is not a problem btw.
good thing i asked here.. i almost bought one of those. i guess ill try to find wireless one that suites me.
thanks again!

Google is your friend as usual, Kidigi are about to launch a Nexus 5 specific dock which is more substantial than the one you were looking at.

Tab S3 as upgrade to Note 10.1 2014 - Your opinions?

The upcoming Tab S3 is the first tablet that I've seen that seems like it would be a good replacement / upgrade for the Note 10.1 2014.
Here are some PROs and CONs as I see it:
PRO:
- battery life
- processor
- "HDR"
- USB-C
- Fingerprint Sensor
- Low weight
- look / feel
- magnetic keyboard option
- 4096 levels pressure sensitivity
- larger rubberized s-pen
CON:
- portrait button orientation
- price
- pen does not fit inside tablet
- pen doesn't have eraser (not important for most, but leaves me using old pens that don't take advantage of the heightened pressure sensitivity)
- Big one: early reviews suggest s-pen input lag
The main con for me is really that custom ROMs have made my Note snappy enough that I don't feel like I really need to upgrade (aside from my aging battery life). With 7.1.1 ROMS (currently on LiquidDeath, but Lineage is great, too) I finally don't get s-pen lag when drawing or writing and would be frustrated to have to deal with that again.
I don't think I can justify the expense right now, but if I had the cash this would seem like a solid choice. Opinions?

I agree with everything you've listed.
I was a bit worried about losing screen size so I calculated some stuff.
Note: 8.6 x 5.4in - 46.44 sq in
Tab: 7.8 x 5.8in - 45.24 sq in
The tab loses a bit of length but gains it back in width. Not going to be as big for widescreen movies and such but hopefully not too bad.
I'm also not a fan of the reduced PPI but I'm going to Best Buy sometime to compare.
The pen not fitting inside is a big issue since it's easy for me to lose them (and the replacement is $60). I would probably put something on its belt clip to keep it attached to me.
However, the pen's gained size may feel nicer in the hand and make it more difficult to lose.
We'll get ROMs eventually. Except if the bootloader is tied down like on the S7 (is it?)

IMO it has 3 big cons not listed here.
Aspect ratio. It's bad for for android. Most iOS apps are optimized for 4:3, so it's a good fit for iPad. Most android apps actually look bad on 4:3 (used Mi tab, apps didn't look good). 4:3 is bad for media consumption. Websites are optimized for widescreen.
Lack of MHL is a big con for me too. I frequently use my tablet as my portable computer (booting linux) or portable media center. I don't find wireless a good alternative (things like chromecast), too much input lag and requires live Internet connection most of the times.
The smaller battery. Sure Note 10.1 has a more power hungry screen and SoC but the difference in battery capacity is so great that with a power efficient rom you always get better autonomy with Note 10.1

Does it not support DisplayPort over USB-C? If not, on Reddit there is a guy with a solution that works for the pixel, which also doesn't support DP over USB-C and that may work. Can't post the link since I'm still new but you can google "google pixel is wired output possible" to find the post.
Went to Best Buy recently and tried it. Couldn't do much since it was locked in demo mode (so I couldn't see how badly apps handle the 4:3 screen) but it seemed like a nice device.
Have you guys seen the Chromebook Plus/Pro? It's a Samsung Chromebook with an Spen, Android app support, and it folds into a tablet. It supports DP over USB-C. Downside is no button on pen. Might be a better fit if you are using the tablet as a portable computer and it will run Linux even better than the tab.

I think only S8 supports video output over usb C at this point. Display output over usb 3 (as per the reddit page) is buggy at best. Tried it to one of my laptops, it's good for quick work, I wouldn't trust it for real work.
Chrome book plus is better for work. But an ultrabook is even better.
It's very bad as a tablet though. I've found out that the further away we are from 500 grams / 1 lbr mark the less people use the said device as a tablet. There is a reason , most books do not weigh more than 1lbr for easier reading. A tablet plays a similar role, the heavier it is the more unusable. Note 10.1 2014 is on the heavy side (would prefer if it had 100 less grams) but still very usable. 1KG tablet/laptops are not though. You may make the occasional tablet use, but no way you get it in the couch for media viewing or reading, or on a trip as a handheld, pretty much why the 2in1 idea never flew (people find that they don't use them as tablets so prefer to go the ultrabook route all the way).

General New adventure starting today (just bought)

So today is the day, after doing good bit of reading to try to study up on the the current crop of potentials for new phone.
Wife and I migrating from H918 LG V20's. Gonna miss the replaceable battery, headphone jack, and SD card slot, but had to do something. Down to about a month now, at least according to the SMS alerts from T-MO.
So picked up 2 LE2125's today. Was looking at few others with the OnePlus 10 Pro as my next choice, but since LineageOS is important in my world view, neither 9 or 10 Pro have SD card slots, and the sands of time running low for my wife's V20, I couldn't wait to see if OnePlus ever got around to releasing a *US* unlocked 12GB/256GB version of the 10 Pro, and anything Samsung is fuhgeddaboudit I don't care how nice their displays might be.
Seems like a pretty bleak time, comparatively, to be looking for a smartphone that covers all the bases. At least compared to features my V20 has. Gonna miss those but if nothing else they might make good network video cameras.
I don't have any illusions about OnePlus/Oppo caring much about what I want in a phone, but I would like OnePlus to know that lack of a 12GB/256GB storage OnePlus 10 Pro US model cost them the sale of 2 OnePlus 10 Pro's today. I was also a bit disappointed in lack of mmWave 5G radios in the 10 Pro while the 9 Pro has n258, 260, and 261 bands, but that wasn't really a dealbreaker for my wife's or my own usage pattern or interests
BTW If anybody at OnePlus/Oppo DOES want to know what people are interested in a phone and you really want to stand out from the rest of the crowd, I bet the market would respond favorably if you put a model out that has an SD Card slot and a 3.5mm headphone jack. I could be wrong, but I don't think so.
These are unlocked phones, we have T Mobile service and SIM's and figure if worst comes to worst for some reason and we decide it is time to move on from TMO, the phones' specs seem to support VZW LTE and the current crop of 5G VZW towers as well. 'bout the only other cell provider we would even consider.
Anywho, the adventure begins.

Wow, a US version or Int'l/EU/India or something?
but yea, I resigned myself to having to buy headphone adapter to solve that problem.

The general public gives no care for SD slots or 3.5mm jacks and these phone companies have made clear that they don't wish to cater to the <1% of their market share that comes from people like us who might care (while I wouldn't object to an SD card slot, I would never use a 3.5mm jack and I haven't had an SD slot in so long that I have learned to live without it) so those particular wishes fall on deaf ears unfortunately.
As for your other wishes, you can find what you want on Amazon. Since you're on the T-Mobile network, it's a great fit.

I get it... headphone jack may not be for everybody. Me, well let's just say that I've got my reasons. For a good long while I was chained to a desk in corporate IT cubeworld, surrounded by noisy people. I needed headphones and a good collection of music to drown out the.... lack of productivity generally going on around me. It was also hard to be very productive in my line of work with music cranked up in my ears, but at least I got to pick the noise, which was never the case there around my desk at the office.
Sadly, in my searching tonight for a USB-C headphone jack adapter, I've not seen one yet with a built-in charger input that you can do both simultaneously (charge AND listen to music at the same time -- or charge and participate in a call over the headset) on a OnePlus, although other brands seem to be able to. So if I ever do have to go back to cubeworld again (hopefully not), especially at the current peanut dispenser, this will surely bite me in hindermost parts at some point, ie, needing to charge AND keep the music going at the same time. Or face the certain peril of my phone having to recharge while the next bagel party is planned or other mindless, non-productive blibber blabber occurs around me...
So I don't see buying a USB-C to headphone adapter as a very good solution. I did find one that looks nice and doesn't cost very much (like a good shrubbery) which I ordered, but I'll have to settle for not being able to charge simultaneously. I'll admit to being a little salty about that.
Musicians are another example of a group of people who tend to prefer wired over bluetooth/wireless monitors/headphones for pretty good reason. Especially drummers. When even what you are hearing in your ears lags behind realtime...
So it has taken me a long time to settle on a phone, lack of headphone jack being among the main reasons. It's funny at least to me how they can justify the real estate for more and more camera eyes and sensors (but still fall so short of truly breathtaking camera performance) -- but on flagship models their marketing people also want you to believe are a pro audio platform, you either have to have bluetooth audio or buy an adapter, because they just don't have the room (or the market demand?) for a 3.5mm headphone jack.
I'm perfectly OK with people not seeing things my way, but in my book, bluetooth cans/IEM's/earbuds are also just something else that have to be recharged when the battery is drained. The marketing people may tell you cords are tangly and a hassle for joggers and other people with active lifestyles -- my take on that is a little diferent. At least when the wired earbuds fall out of your ears, they are still attached to something you can probably grab before they get away from you.
The SD card slot, well it's another thing related to having a decent music collection on my phone and room for backups and various root/mod/etc things handy without using up the device's storage. But with 256GB I will survive. I would not have been able to suffer 128GB though.
These little obsoletions are the sorts of things they call "progress" these days. I tend to have pretty good reasons for knowing what I want. It's just getting harder and harder to find anymore. I'm pretty used to the world going the other way though. It's just really been picking up the pace lately.
But at least I was able to find something well supported by LineageOS and by what I've been reading around, has decent moddability and tools etc.
Hopefully these will last a good long time.
EDIT/PS: I sat down and compared the radio band support of the 9 Pro and 10 Pro, along with coverage bands my current carrier TMO and the only other one we would ever consider switching to supports (if TMO really goes bad somehow, VZW would be most likely escape route but we are not really big VZW fans after many years of customer abuse, why we switched to TMO) . There's not much of difference between 9/10 for bands support really but for those times we do go out and about, those mmWave bands the 9 Pro supports would be useful, and are used/supported by both carriers we care about in our area.

Something like this Y cable is what you would need.

I see your argument for 3.5mm, I'm just saying most consumers have moved on to Bluetooth. My Sony WH-1000XM3s have a 30 hour battery life so it would be near impossible to kill them without an opportunity to charge them and I'm plenty happy with the sound quality.
mmWave is largely useless on T-Mobile. I wouldn't make a decision based on that since the coverage is insanely limited. T-Mobile's n41 midband is what you really want.
EDIT: Actually, looks like OnePlus killed the ability to charge and play at the same time in software. It died in 2020 and was still dead in this thread so you may be SOL.

Yep, bluetooth may be more practical or convenient for others.
It's a shame about the inability to charge and use the headset at same time. But I see this as another example of... well, it could be a lot things. But it wasn't that long ago at all that a simple thing like that would have been a given. Something you could take for granted within a phone's specs or capabilities because, the people defining criteria or design for a phone were not developing in a vacuum. It was just common sense.
Over the many years I have been paying attention and participating in technology at work and at play, there seem to be less of those "no brainer" type of givens. As if the people designing things don't ever use them, and aren't listening to people who do use them.
Great example, totally unrelated but it really reinforces the point, at least to me. Our car is a Hyundai SUV with an "ultimate" package of features, trim, etc. One of the most insane, ridiculously stupid things I have ever seen in the interior passenger compartment of a car is the simulated wood trim the dashboard of this SUV is festooned with, from left to right.
Some genius at Hyundai, or a whole team full of them, probably all with college degrees in marketing, sociology, or business decided that the top of line model of this SUV needed to have a super high-gloss finish on all of the interior imitation wood veneer trim. In their minds, this is probably the pinnacle of bling - I can almost hear them saying "ooooh, shiney!" This was their idea of luxury.
The reality of the matter is quite different, however. As the owner and driver of this vehicle, I dread driving on sunny days when the sun will reflect off the dashboard AND BLINDS ME WHILE I AM DRIVING. Right through my sunglasses sometimes.
Of course I am aware of this and it seldom catches me off guard. But it is inevitable that circumstances will (mis)align from time to time.
Anybody who had any sense would have never put high gloss finish on anything around the dashboard on the interior of a motor vehicle. Nobody in the 60's did. (I used to work on old classics)
But if you asked them why they thought high-gloss imitation wood veneer on the dashboard was a good idea, they would probably have several reasons that would make sense to a lot of people. People who don't have to drive one of them every day....
By the time we realized this was a problem it was too late, the car was ours and the paperwork was signed.
There used to be a lot more things you didn't have to research or think about so hard when you were shopping.
Sure do miss the good old days.

PS: The mmWave support of the 9 Pro wasn't really a make or break feature for us, we aren't out and about all that much anyway even if they do have a bunch of those towers in the (2nd largest in the US and fastest growing) metro area we are kind of stuck living in right now. Just that we might actually get some use out of it from time to time. I *KNOW* I'll definitely make use of the extra storage on the 9 Pro than can be had in a US market 10 Pro model.
I came close to choosing one of a few Motorola unlocked models that were semi-interesting but none of the ones with some attractive specs really quite did it for me. There was always something that killed it for me, like the problems so many reported with green screen tinting on many of the edge models. Or the models that might have had other desirable features and compatibilities, but only supported one carriers tower coverage very well instead of 2 strong players around here.
I know a lot of people aren't really interested in many of the same things I am -- but the case can be made that what a lot of people don't know or realize is how much of what they think THEY want is actually due to marketing and media influence and manipulation -- people TELLING you what you want and how to think -- and how afraid so many -- manufacturers and consumers alike -- are afraid to take even the tiniest of risks and being the nail that sticks out -- everybody is afraid they'll get hammered.
In the end, originality and thinking for one's self become bywords and, oh my goodness, nobody wants to be accused of being "UNSCANNABLE!!!!" (Idiocracy, 2006) or going against the grain. And so it's a lot easier for a lot of the lemmings to end up in a pile somewhere down there below, just outside of public awareness and the news cycle/drumbeat.
i won't apologize for thinking that (proverbially, continuing along the Idiocracy story line) using Brawndo for everything but flushing the toilet with is just stupid. If that's how everybody else wants to go, OK fine, but I really shouldn't have to go to the toilet to get plain old water for the things people used to use water for when more things in life "just worked".
I just wish I had better choices. I don't see that many of the choices being offered these days are coming from people who think about things very much, or know how to plan and execute well.
Anyway, enough of the blabber, I am actually looking forward to getting started with our Oneplus 9 Pro's. I haven't even broken the seal on either box yet - but trying to line up all the info I can to get a quick early backup of the devices before I do much.
Appreciate the conversation!
