No reason for me to upgrade at all. XP does me fine for what I use my PC for these days. That totals: photoshop for photos, email in thunderbird, and firefox for flickr and forums. Maybe one day, but I ain't rushing. I'll get it at work shortly I'm sure. If that happens and I really like it I might consider switching, but problem is I've just read NF3 isn't being supported for Vista by nVidia and I'll be damned if I'm upgrading hardware. tbh, though, I've been wanting to switch to Linux for a while, it's just finding the time to implement the change. I'll need to keep dual boot with Windows for PS, but apart from that it can go. But it also makes me think of going OSX. Using it on the bird's iBook, it is pretty nice and runs all the above that I need. Problem is, OSX requires new hardware like Vista. Linux is free.
