Nice! You should definately think about getting Xbox Live. There is so many bonuses to Live it's crazy, I can't believe I ever played without it on 360(actually I didn't...I got live the day I got my 360...but still.)
Well I have absolutely no idea how to use XboxLive as I've never used it but hopefully it isn't that complicated...if it isn't I'll give it a whirl and see how it works. But the first thing I'm gonna be doing is getting all my original Xbox games onto the 360...the backwards compatibility feature, again hopefully it's not that complicated...
