Sorry, that's not the future for most people. Even apps like Evernote and Spotify and what not are really, really hard to cram into a teeny tiny screen. It's not a great experience. Then if you consider internationally how many people use their phone as their primary, if not exclusive, computer and yeah. That's just how it adds up.

App developers no longer have to worry about 320x480 resolutions. They effectively don't worry about small from 3:2 aspect ratio displays. Soon they won't have to deal with it at all. For the vast majority of users this is a good thing. For a slim minority it's a bad thing. =[
