I dunno, I have RC1 installed (soon to be RC2), and it works quite well for me. It boots up much faster than my XP, it's just as snappy as XP, and it seems to run games fine. The games I am currently able to run are Need for Speed Underground, Condemned, FEAR(weird slowdown issue after a while), Dark Messiah of Might and Magic Demo, C&C Generals, Oblivion, Morrowind, San Andreas, Half Life 2, and The Sims 2. I tried some other games (COD2, Rise of nations.....) which didnt work, but that may have been because I didnt actually install them on Vista, I just ran the exe from my XP partition. All the games I confirmed to work are just running from my XP install (except Dark Messiah and the Sims 2). There are still a couple programs that dont work, but a majority of the programs out there do work. I personally can live with Vista just fine, and now It's XP that I can't stand. Don't know if you'd feel the same way, so you'll just have to try it. If you dont like it you can always get rid of it.
