I don't understand why everyone hates Vista so much. It came pre-installed on my laptop and I love it. I haven't encountered any problems so far and my computer is 2 years old.
I've been using Vista for about a year and a half. When I first started, I absolutely hated it. Couldn't stand it and desperately wanted my XP back. After a while I adjusted. Now I actually like it quite a bit and find that using XP computers feels off to me.
