You won't find anything worht using other than Linux. Download OpenSUSE 10. It is the easiest Linux distro. You can get the commerical version for $50, but Novell also released a mainstream stripped down verison which isn't very different from the retail. Download that, I tested it out. I liked, but since I've been using Linux for a long time, I'm more used to a power distro: Gentoo [don't try this one, you'll be crying].
