My boxes run Windoze.  I just RDP to them if I want to see what's going on, but generally unless I spot a problem in the stats (I use Slush's pool) then there is no need.

I tried to get BAMT going and, despite being very proficient with Linux, couldn't even get the USB key to build properly.  Much as it pains me to say it, GUIminer on Windows 'just works'.
