I have a T61 thinkpad, and love it. I use Linux on it solely. I have compiz bound to those forward and back arrows as cube_rotate_left and right. And I also run 8 desktops. Makes my world so much simpler in terms of organization of programs and flow.
Fellow T61er on Linux chiming in. A thousand MBAs couldn't tear me away.
Nice idea. So going to do that on my spare T61 later :)
