This is neat, but both Android and iPhone are really poor choices if you're looking to travel with a computer. Particularly on the iPhone side of things, you're basically screwed if you lose your network connection, since you aren't going to be doing many interesting things with the local shell. Android is a little better, but you'll still end up SSHing into another machine to get any valuable work done.

Good, cheap x86 laptops are like $80 right now. That's about how much you'd pay for one of those fancy Logitech keyboards, but it comes with an entire computer, too.
