Myself, I like 360 because of what microsoft wants to do with it and how they do it. Sure they want to control your living room, but if they are willing to lose alot of money to do it and buy you out, I say go ahead. Sony, well, they also want to control your living room. But the difference is that they want you to pay them your life savings and your unwashed used panties to use for their weird sexual acts (They are Japanese, they do that crazy stuff, if you don't believe me, watch Shocking Asia).
All kidding aside, I have both XBox and PS2. I would like both of the next gen system. But if I had to pick one, I'll stay with the 360. It's cheaper and their graphic is the same. Don't believe the hype of the PS3 graphics, its like comparing the latest from NVidia to ATI's latest, it all comes down how the developer's uses it. Also, Sony's exclusive titles are almost gone, Grand Theft Auto will come out for both systems at the same time. Sure sony got God of War, but Microsoft gots Master Chief.
So, it's all really up to you. If you want a console, get 360 because it will be cheaper. You get more bang for the buck. But if you are serious about being a gamer, want alot of options for games, have some money to spend, and don't want to look immature by playing video games, get a PC. The PC (personal computers) can make good excuse. If your wife/hubby ask why you bought a new PC, you can always go with the the "The kids needs it for school." excuse and just don't metion the $600 video card. Also, there is no limits on the games. You will NEVER see Galactic Civ on a console. And you can do alot more than just play video games on a PC.
