Businesses will have full Windows Vista final version in November (next month) while all other consumers like us will be able to get the final full version in January of 2007. Just two more months and we won't have to deal with RCs.
I'm downloading it right now, but it's the RC1 version. I finally got the confirmation email from Microsoft with the product key on there so it should be good to go once it's downloaded. I got the 64-bit version of VIsta so it's got to be an improvement, if I can find the drivers for it.
