Xp64 is immature, vista 64 is far better but you will have driver problems at some stage with something for sure. They only got a 64bit compatable iTunes going last month for example. It wouldn't even install before that. Drivers are at the discresion of the manufacturer. My canon scanner isn't that old but they have decided not to provide 64bit drivers to force you to buy a new one. The Bistards ... I just moved it to my unix server and share it on the network
