Ok, strip away my political implications on this. Does anybody ever think this has a snowballs chance in hell of happening?
In addition, the reasons phones are getting larger screens and thinner and smaller dimensions is due to 'all in one' chips and miniaturization. There is no way a real live phone built in modules could be half as thin as an all in one integrated solution.
That's why modern laptops and phones aren't upgradeable.
The reason why the iphone and HTC One are so 'sexy' is because you give up the ability, unlike the Galaxy phones, to pop off the back cover and replace the battery or SD card.
Plus, like Desktop PC's, 90'% of the time, you find its cheaper replacing the whole box, than adding more ram, changing the graphics card, putting in a new hard drive, upgrading the power supply. When you add it all up, its better getting a new unit which at the core level takes new advances into account.
I distinctly remember a PC sold exactly like this, I think it was the early 90's and it flopped royally
