i've been running Xp for months - through the beta incarnations, the RC releases and finally the finished version. I have had very very few problems - its perfectly stable and my PCs are used (not just on) for about 15 hours per day. Not only that but i have a whole host of peripherals hanging off my main workstation - two scanners, digital camera, digital camcorder, ipaq, printer etc etc, - i had to look on the canon site originally for my scanner drivers but thats all. The only problem i did have was that the drivers written for the Aureal Vortex (as the company no longer exists) only support the first out speaker port (and my speakers at the time were plugged into port 2)
