The XBOX 360 Elite is one sweet little machine! I'm very impressed with it so far.
The XBOX Live functionality is particularly impressive. Microsoft has done a simply fantastic job with the entire platform.

Orange Box is a lot of fun on the 360... especially TF2. But I have to admit, I find it much more enjoyable on the PC version (more custom maps, custom spray paints, etc).
Another thing I foud super-cool was the ability to stream my music library from my laptop over WiFi as the music in games. Very cool, but I had to strip off DRM first, since most of my lib was in iTunes. A piece of software called "Tunebite" does a great job and makes short work of that for just a few bucks.
I must say I've spent a lot of time in PGR4 now and Flatout UC. Guess I've got the racing bug :)

See you online!
