I made the switch about a year ago and this has been the first year I haven't had to reinstall clean since windows 3.1 in the early 90's. I've created and kept a lot of documents since the late 80's and early 90's that I have transferred from computer to computer, OS to OS and XP with its activation and the DRM stuff that has the potential to be in the next version of MS office and the annoying bugs in XP helped me make the switch. I spend so much more time now actauly using my system to do things I want and not installing updates, and keeping the spyware removal and antivirus programs up to date (I used to spend an average on one hour per day just on computer maintenance)
