It is almost two years ago that i decided to uninstall Vista after a bad first impression. Nowadays i have learned to live with it, but i guess i will never understand what all the fuss was about.
I can imagine that the marketing department will generate a lot of noise about Windows 7 but i am not convinced that there are actually people waiting for yet another OS. Anyway, i installed Windows 7 somewhere last week and i must say that i am pretty pleased with it. I guess that you didn’t see that one coming, do you? Me, finally liking an operation system that comes from Microsoft 
PS: Forgot to mention that i do not like the fact that i can not have Windows Virtual PC and Virtual Server 2005 at the same time :/
I am in the same boat – ever since I bought HP laptop with Vista on it I had nothing but frustration with Vista. So, I am pulling my butcher knife this weekend – bye-bye Vista! I will give Windows 7 RC a try and if I don’t like it either – back to XP with no frills or WOWs.
