I was part of Vista Beta Review plan which was passed on for beta testing to MSDN premium subscribers in July 2005. I installed Vista in September 2006 and am using it since.
I really find it strange that people will try to pull down Microsoft at the drop of the hat!! Can anybody tell me that somebody forced them to use Vista? Can anybody tell me that Microsoft Vendors didn't gave them Vista Premium and forced them to buy Ultimate on gun point? Crap!!
Everybody is working for money. The sooner you get it, the better.
Vista is the best OS from Microsoft till date. The problem that not many people can't find it is, they are still mired in looking at the eye candy and trying to transport that eye candy to XP. Vista is much more than eye candy. There are so many changes that you cannot count.
It all depends on perception. How you perceive things.
Get over it. If you don't like Vista than don't use it. Period.
No hard feelings and no flames.
@Udit: I really give it to you mate. You are some of those people who stood out for Vista from day one and never changed your stance.

Cheers.
