Seems pointless to me. By the time the elites came out they had the RRoD problem fixed, and you already have 120gig hd, do you really need 250? Built in wifi, whatever, thats probably the 1 good thing. Kinect ready, oh boohoo, all regular users have to do when they get it is patch it / install a cd and there xbox's are kinect ready.
Wouldn't be worth it imo to go sell your perfectly fine xbox for another one, then having to pay money out of hand for the same thing you already had?
I don't get it, unless WiFi means THAT much...
