> But my next phone will be an iPhone.
I'm seriously considering my next phone to be one I build.
The hardware is available - cheap 4G LTE modules that plug right into a Raspberry Pi Zero exist; that and a cheap touchscreen will get you around 90% of the functionality most of us need, hardware-wise. You won't have a camera, or motion sensors. You will have GPS, voice, data, a screen, storage...
Basically everything you need for most purposes. And adding a camera and an IMU isn't that difficult, either.
The difficult part is - as always - the software. But people out there are building those pieces. Quite a bit can be done using plain-old Raspbian and Python on top, because the cellular module is essentially a virtual serial port device, and everything else has simple drivers or is otherwise easy to interface to.
Where I'll probably start, though, is with the idea of a custom "cyberdeck"; I already have most if not all of the parts, I just need to find the time to do it. It's form factor will be close to what the TRS-80 Model 100 was, though the screen will be...well, different. I'm considering a few options; probably a standard 800x600 HDMI screen along with a secondary 128x64 monochrome serial GLCD.
The ultimate thing about the whole project is independence (well, as independent as I can get - still have to pay some piper - aka T-Mobile - but maybe voip over wifi could be done in the future?) - and customization.
I may not have everything I want in the beginning, but what I want may only be a bit of extra coding, a tad bit of soldering, or likely a bit (or a bunch!) of both. I'm honestly tired of the games Google and pals are playing; kicking them to the curb may be the best thing to do.
