No need to bash Vista at all. All you have to do is look at the bug lists for it. That speaks volumes for the problems Microsoft has with it and why so many people are having troubles with it.
I figure anyone saying they are not having any problems are just unaware of the problems they are having. Given time, the problems will finally manifest in a grotesque manner.
Not saying that you cannot work around many of the bugs. But to do that, you have to acknowledge they are there.
