Wow, $119. for the home Windows 7 Upgrade. I want it but I will wait a while to see if there are problems.
Best Buy is offering a 3-system home upgrade for around that.
The "upgrade" requires a fresh install when you go from XP, but Microsoft had a nice little free program that grabs your profile and anything else you want it to and saves it in a file on a jump drive, then puts it all back where it needs to go on the new install.
Overall, it was the most painless upgrade I've ever done. I'm really liking it. My system really smokes now with the 64 bit version!
I have't read past your reply yet, but I'll bet there will be someone talking about how a free version of Ubuntu is just as good. (Well Ubuntu WILL run on a 386 with 64Mb of memory!)
Or for about 3 times that, you'll be able to get a decent new computer in January with it already installed.
