I bought Thinkpads for work, installed Fedora on them and everything worked out of the box, right down to the keyboard backlight dimming.

The things you have to watch out for are: * Use an up to date distro with an up to date kernel (e.g. Fedora) * Graphics are the only real driver issue. Easiest solution is to buy something with integrated Intel, but some cards are well supported, you just need to check * Battery life will be worse compared to Windows on a machine normally sold for Windows. This situation may be better on things designed for Linux, like Dell Sputnik stuff and Purism, but I have less experience with them
