I run Windows XP Pro SP2 under Bootcamp. My main complaint is that I use a bluetooth keyboard exclusively and when I'm booting into Windows, I can't type my username/password with the bluetooth keyboard. I have to go looking for a USB keyboard either in my son's room or in the basement family room (where my old iMac is living now), so I don't use it much. It's really a pain that Windows can't boot with a bluetooth keyboard, IMHO. <br><br>My 2 cents...<br><br>
