I just upgraded to Windows 7 RC last night and, everything is working fine so far except for the digitizer. I'm having issues with accuracy mainly (and of course the random occurrence of finger input turning off but N-Trig already addressed that). The only way to get it accurate again is to reset the pen calibration completely and recalibrate it. I have a legal key and ISO of Windows 7 Professional I received from my college and have been wondering if perhaps a clean install using that could alleviate my problems? I'd rather not do a clean install unless it would solve this. I also have the random phantom cursor issue sometimes but after the last reinstall of the N-Trig drivers for W7 it appears to be gone...for now.
