I just got a T400 for Linux development last week, so I read this headline with not a small amount of trepidation. Fortunately I fall into the author's "Linux-powered typewriter" use case: I spend 80% of my time in fullscreen (using xmonad) bash or vim sessions, using white-on-black color schemes. For my development machine I don't really care about color fidelity or dynamic range.

The reasons I like the T400 (and many of its Thinkpad siblings) are the trackpoint ("pencil eraser" mouse device), nice keyboard layout, and hardware that works out of the box with open-source drivers. I have had some intermittent freezes on suspend/resume, which I hope are fixed soon...
