Um, sad to say that I haven't played video games in 10 years and am now getting back into it! Most of my friends ahem aren't gamers.
What do you want to do with it? I'm mostly a PC gamer and use my PS3 for streaming media from my PC to my TV, as well as watching blurays and play the occasional game. Both could fulfill this job, so I guess it could come down to which of the exclusive titles you want to play.
I mostly want to get back into gaming and spend some time with my teenage son online. At first he will kick my ass, but I have to believe that I'll eventually get up to speed. And if I don't it'll be something he can laugh at me about. I mean, he needs a 1up on me too, right?
What does your son want? He may want to play with his friends online.
I could have knowingly paid good money for hardware I'm not allowed to tinker with, but that would be hard to reconcile with who I want to be. So I dropped a better video card into my PC.
