I run XP Pro on my main system, mainly for the native digital photo printing built right into Explorer. My daughter's system, and my laptop have Win2k, and I have another box that I run Gentoo Linux on. As of March of this year, when an app was released that sync's my Pocket PC 2003 equipped PDA to my Linux box, I could totally live without the XP box. I have been a firm believer in Win2K since it was released, and I hate that MS has such limited support for it.
