Damn you guys for making me jealous. Picked one up. This is SEXY! Pictures don't do it justice.
Regarding the wifi, before I used to be one bar short of full, now it's all the way. Transferring data from my old hd is practically one easy step. The new Xbox even detected the old hd once you hook it up via transfer cable.
Like everyone is saying, the fan does get warm, but that's the only part. And you can feel cool air being pulled from the top of the Xbox (vertical stance). Best of all....quiet!!
Also, read somewhere that there was a new Xbox intro, but it's the same one as before.
