I'm doing all my work (programming) on my trusty ThinkPad x200, which is basically a successor to X6x. While it is somewhat larger (12" screen, 3.25lb), it's still rather mobile, and a bit bigger screen (1280x800) means I can fit most of what I need on the screen (I prefer my windows maximised, though, and my IDE of choice is vim+bash). It's powerful enough machine, too - I usually have one (or, not so often, two or more) VM running for servers and/or different operating systems.
