Over rated? Not according to the people who still play it often on live. As far as being controlled, biting because of advertisement and because its cool? Well, talk to me after you stop spending $400 every 6 months on the newest and greatest vid card. Thats just a ridiculous assumption. I want one for one reason only. I did my research on it, and not normal research... very indepth and technical research. What this console is capable of doing wont be fully realized/fleshed out for a few years. Also, I'm not into buying ad campaigns. I make my OWN money, and work in the IT field. I also spend lots of money on my system. Many of those who buy the 360 are also avid computer users, like myself. This arguement is foolish, and is not backed by any sort of proof, just mud slinging.
Oh yeah, supposedy 3rd party companies will release mouse AND keyboard support. Mostly for MMORPG, but I'm sure it will eventually if not right away be used for FPS as well, as you just need to use the mouse tracking axis to simulate the controller axis (kbd, too). If the popularity of it xplodes, then I'm sure youll see MS and the software designers take up on it.
