It makes sense, really. We've reached a point where the average consumer doesn't need all the goddamn horsepower you can buy anymore, either in a phone, or a desktop, or a laptop, or a tablet. If people had discipline about photos and videos they'd never need to upgrade again, other than the pernicious habit of making ever-more-resource-intensive operating systems.

But something like this would just about solve the problem. Build two, maybe three buses - a girl-sized phone, a nerd-sized phone, and a texting flipper. Give it three slots (two front, one back) for cameras. Give it a wireless slot. Give it a charge/IO slot. Give it a battery slot. Give it a speaker slot (or two, 'cuz people think you get stereo an inch apart FFS). Build it all around a memory slot, a CPU slot, a GPU slot and three different sizes of screen slots and you're off to the races.

It'll take a company like Google or Amazon to do that, though, because in order to pursue this model you have to be hell-bent on annihilating your competition through forbearance of profit.
