I played a few video games a coupla years ago, had my place in San Luis Obispo set up like a sports bar right downtown so people could play it on my HiDef Tv when the sports werent on while I grilled 100 chicken wings and thighs on my grill over looking the river.
Havent played since, still have the TV and now Im getting a 25foot capable projection that can be run windows media pc based. Meaning, I throw my laptop in my duffle bag and throw a party with a drivein like view. All that stuff has to be interactive or its, this works here, but not there, incompatible this or that.
Going with the xbox means you have another computer for the digital media center. Hook it all up, its amazing. 21st century dude, get with it.
All of this computing power, why limit its applications by going with a PS3 when you can have that run your video and photos albums and surf online on a giant screen wirelessly by remote or whatever.
Xbox, just adds to the megacomputing system. PS3 for neophytes, xbox will answer your phone and run your a/c and appliances by voice command while your a hundred miles away
