I am in the process of switching from Windows XP to Linux. I installed in the first of 3 computers yesterday.
A couple of caveats though...
My flatbed scanner only has windows compatability and I didn't want to purchase a new one to replace it so I set it up on an old XP computer (not connected to the 'net) and scan to a thumb drive to use with my linux office programs.
I also ran into an issue with a video card not supported by linux so I just replaced it (cheap) with a newer one that is supported. Once you iron out the little things you'll find linux to be a very stable operating system.
Oh,yeah, by the way, any new computer accessory I purchase has to have a linux compatability logo on it or I don't buy.
Of course, there is still FR as well. Don't forget to donate! :)
