^ LOL, if you're looking for something practical you should come back to this thread in a year. The months leading up to a new console launch is all hype, pouring over the tidbits of leaked details, and arm chair analysis to the extreme.
Hell, Microsoft has changed their business plan and messages so many times who the hell knows where it'll be in a year.
Honestly though, my concern with the system is the sheer amount of hot air the thing has to dump through the top. With the hands on-time I had with the system, that really stood out for me. Who knows if they'll fix that for the actual launch versions.
