Now on Windows 7
I installed Windows 7 Beta to my old home machine. Basic installation took 25 minutes approx.
I had slight issues with display drivers since this mummy display adapter (RadeonIGP9100) hasn't worked even with Vista (ever). Well, with nice tip from here I was able to get it to work somehow - no Aero but I don't mind :-).
Another source of issue was Windows Live Messenger. Starting Messenger hangs the machine to 'reboot condition'. So as long as I use it, it's now web messenger, not the real one, unless the issue is solved somehow. I googled that could also be related to display drivers, but so far only MSN has got the machine to hang...
This is what I have so far. I'm impressed, very stable product to be at beta stage.
