Quoting Sledgehammer70

If I can't upgrade my PC than i won't be buying Vista... I upgrade my PC to many times to count... they better have a way for us Hard core PC guys to be able to upgrade and not worry,or Cracks will become very popular....

Yeh, this is rediculous. I expect a 3rd party workaround fairly quickly after the release. I dont upgrade that often, but even at that, I do it 2-3 time a year, so is MS telling me Im going to have to buy a new copy every 9-12 months? sure....
