Party chat has been the best thing ever, i know all you xbox traitors had it but damn it's good!
I know there aren't a lot of games out for it yet but i'm glad i've got one for when they do. Don't want to get to a point where games start flooding out and i want to buy them all but need to get the console first. Buying early is definitely worth it if you enjoy playing many games, instead of saving for a console i'm now putting money aside for about 5 or 6 games.
This is actually the main reason for me, i know not everyone has one yet but the fact so many of us have or are getting one just makes it so much better. Glad you guys eventually saw the light
