I was going to call this post "windows 7 Trial Report," but I guess I don't have much of a right to call it that, since I've used XP most of the time and haven't used vista in depth. Only that vista's UAC is annoying.
According to statistics, the majority of people who browse may use XP, so if you plan to upgrade directly from XP to win7 in the future, you can see how I feel.
