Vista sucks. When it comes time to upgrade my OS, I'm switching to Ubuntu or some other Linus OS, and maybe in time, Windows 7.

Vista is slow. Vista can't run very many programs. Hell, my friend has vista, and whenever he tries to watch a Stage6 video (hi-def youtube, essentially), his OS switches themes. Programs I use just fine on XP, common programs that a lot of people use (like Team Fortress 2 and Final Fantasy XI) randomly lock up his computer. It's not a performance issue, as his specs can run games like Oblivion (very intensive graphically) at full settings, but games like Final Fantasy XI, an older game with old graphics, cannot run so smoothly.

Nothing but problems with Vista.

Not to mention how Vista essentially holds the user's hand :/
