I installed Windows Vista Ultimate on my 2nd computer with an AMD Duron 1.6GHz and 512MB PC3200 RAM. It ran good and I checked it out. However, the only thing major difference I saw was Aero which is basically a Windows version of Beryl. It has media center stuff built into it too and voice recognition. Overall, it has way too much crap that people are probably never gonna use and most people will probably need a newer computer to run it. I wouldn't recommend it until you really like the fancy graphics. I don't have any screenshots to show, sorry.
