So... Here's what I might do and am worried about.

I'm running the RC, build 7100. I might just be getting a new laptop with Windows 7, but in the event that I am stuck with my current piece of $&%^ for longer than until it starts rebooting, I will get a 7 upgrade. If that upgrade fails, I can still do a "clean-upgrade" over that install, correct? Of course, if all else fails, I have my Vista OEM recovery discs to go back to Vista...
