Me three. Not worth it anymore. Maybe if they came out with a new Halo game I would pony up the cash, but even then not likely. Eop05 made a great point. I forgot to point out the wireless adapter. They still haven't dropped the price on it either. $100. Sony's is built in. If you're buying a system and plan on playing online the Xbox360 is more expensive right off the bat, and factor in all the nickle and diming Xbox will hit you with and Xbox will end up costing you hundreds more over the years.
The xbox does nickle and dime you (charge kit anyone? yeah i bought two, screw it) but! You can do wireless for cheaper. Look up wireless bridge and 360. You'll be on your way. I don't like wireless for any of my computers or consoles, except my laptop just for surfing. Dunno, I just remember the latency hit on them from my counterstrike days. I also only use wired mouse for gaming as well. Guess I'm old school in that regard.
I have a problem with the idea of rewarding a company for pushing out a product with a 40% or so failure rate. To me that's unacceptable. I don't care how good of a game Halo is or how Live is or any of that. If they put out a better product in the future I will certainly consider buying it. Right now I'm perfectly happy with my PS3 that I've used daily for a year and a half now with no problems.
