Although I love my touch devices, one thing I've noticed is that they are a major disincentive to writing actual paragraphs. On screen keyboards get the job done, but if I have to scrawl more than a Twitter length reply to someone on a tablet or phone, it's so much effort that I just avoid doing it altogether, postponing indefinitely until I can be in front of a keyboard. By the time that happens I've probably forgotten what I wanted to say in the first place, or that I even needed to reply at all. Multiply that by millions or billions, and you have a whole generation technologically locked into a backwater of minimal communication.
That “whole generation”? They’re not as attached to keyboards as we are. They’re going to take what they have and make those touch keyboards sing.
