Have to agree, the Ubuntu distro, a variant of Debian, is a really familiar feeling Linux OS. I prefer KDE to GNOME, making Kubuntu one of my preferred OS (also use Mac and Gentoo), but I am logged in and posting through GNOME now.
CotD, you do not have to switch to another OS, a well-maintained installation of Windows can be as safe as any other. Windows 7 is actually quite nice and reminds me of Mac OS X. If you have it installed, doubt you need to switch. But, I do recommend a second OS on your machine, just for backup.
Hope you were able to fix the 'puter.
