I think this is like any upgrade or change of the Windows system. I will wait at least a month (probably 3 or 4 months) before installing Windows 7 to see what fixes will occur, before I install the windows 7 system that I received today. It definitely seems to me that a clean install of 7 is the answer, so I definitely won't upgrade Vista. BTW, I have no problems with Vista, but probably don't use my computer as much as most.
I know it is difficult to wait and I want to see the new Windows speed etc. too.
I hope all of you, like Bob, will have a good experience with installing Windows 7.
