I use a ThinkPad X60 and Synergy as my "keyboard". I've had way too many keyboards over the years, but the X-series ThinkPads are the only ones that don't make my hands ache after a day (or night) of code wrangling.

Alas, I can't comment on which modern ThinkPads are best. I know for a fact that X40 and X60 lines are perfect. I've never used an X200 though. On the other hand, I've had a T400-something from work for a few months. That keyboard was worthless compared to my current X60.

If you like thinkpad keyboards you might be interested in the usb version: http://shop.lenovo.com/SEUILibrary/controller/e/web/LenovoPo... A colleague of mine swears by this, he says its just like the X60 series except bit bigger and can be placed at an angle. Nice touches are the inclusion of volume control and the trackPoint.
