Just got an Xbox 360 set up with the rest of my consoles. Some quick first impression notes:
The original Xbox Wireless Bridge works just fine with the 360.
An optical digital audio cable is not included. Glad I had a spare one.
The 360 is pretty noisy, but not much more so than the Xbox and PS2. Fine for gaming, but not for music listening (so much for the "multimedia hub" idea).
This must be the ugliest video game console since… the original Xbox. Luckily, it has interchangeable face plates, but there aren't any nice ones available yet.
I now understand the reason for the curved body shape. It is the only device that sits perfectly atop the original Xbox without sliding off its curved top.
I'm anxious to see if it can talk to a non-Microsoft UPnP server.
