I like Xp purely because Vista seems to take an age to load up on the PC while my laptop is ready in half the time. Most of the things I need don't seem to be very different, so there must be a lot I'm not using. We did have to have a wireless internet connection with vista because a lot of the modems with usb's aren't compatible, but apart from some older software not working, it's really just a matter of getting on with it because microsoft sets the pace and we jog along with it.
