I'm running Vista Premium on my aluminum iMac. Everything is fine but bluetooth works so much better under OS X than Windows. When I boot into OS X my wireless bluetooth mouse and keyboard can be used immediately and the iMac can be awaken from sleep by either pressing the mouse or any key on the keyboard. With Vista it takes about 30 seconds for the wireless mouse and keyboard to pair and neither the mouse or keyboard can be used to wake the iMac. Is anyone else having better luck with bluetooth in Windows than me?
