Despite assurances to the contrary, my Apple Pro Wireless keyboard and Kensington Bluetooth mouse worked just fine under Windows XP on my MacBook Pro 1.8GHz, even in the DOS installer and even thru reboots, until i installed the Apple Bluetooth driver. After installing the Apple drivers, I had to re-pair the mouse and keyboard with Windows, but they both continue to work. They even remain paired when changing operating systems back to MacOS X. Overall I'm very impressed.
