I agree with your first sentence: Windows 7 is a vast improvement over Vista. But, then again, that's like saying a worm is waaaay smarter than a rock. They're still both Windows; and with Vista it's really not that hard to beat. I tried the Windows 7 thing when the beta was available, and
when the download site finally starting working, Windows 7 - while an improvement over Vista - still gave me problems (eg: Not installing without problems, crashing in the midst of regular use, OS hesitation, etc).
I don't quite understand why people make the statement that Win7 is better than Vista, and use that as an argument to get people to upgrade or use Windows. Windows 7 is what Vista should have been in the first place.
...and just on a personal note: I don't like the Windows interface anyway.
But,
OP, you think Windows 7 is the cat's balls. Kudos. I wish you all the best.
