Anyone tried running P7 in Windows 7?  I'm not sure why it wouldn't work unless it was version locked, but you never know.  I have the beta running as duel boot.  So if no one else has tried it I can check for myself.  But I'm not sure if SM is watching installs on a given serial number.  So I'm hesitant to install if I don't plan on keeping the OS build (I've rebuilt my main system twice this year... if they are watching, my activity probably looks pretty sketchy).

I'm building a new system that will probably come online around the time Win7 RC1 is released.  So unless there are any show stoppers with my apps, I'll probably just go with Win7.  I love it so far.
