*snort*
I have a Linux install here, it boots from a memory stick on my Thinkpad. I only have it for one reason, and that's to configure my travel-router so I can use the Thinkpad on wifi networks.
I did try to use it as an everyday OS to save carrying 2 laptops around when I'm working away. Didn't last long, 'cos Linux is clunky, in no way user-friendly and looks like the amateur beta release that it is.
