Install went smoothly from a Plextor PX-610U USB-powered DVD/RW. Build 7022. Running Windows update found all of the uninstalled drivers, including an Intel 945 pre-release WDDM driver, and a prerelease infrared driver. All the newly found drivers seemed OK except for the new Intel 945 driver (Error 37). I rolled back to the 7022 installed driver and the 945 chipset seems OK. The screen rotates and the brightness settings are available in the Windows 7 Mobility center. Didn't have to go looking for any drivers but I don't see Bluetooth enabled so maybe that's something to investigate. Windows 7 navigation, as expected and experienced by others is quick. Windows 7 seems to be the "real deal" -- so far.
