My argument isn't that touch devices haven't taken off, nor do I argue that ubiquitous internet isn't a huge deal for the pocket computing market. I love my new Nexus S for those reasons, and I'm sure if Palm had had those features ten years ago, we'd be in a different place today.

My argument is that---regardless of those features' importance for pocket computing---they haven't changed the game for tablet devices. Tablet devices remain wedged in that space where they're too big for the pocket and too small for the lap or desk. If you're going out, take your phone; if you're staying in, you might as well use your laptop and get some work done.
