Slash the price of the consoles and games by two thirds and i would maybe get one to play with, but as it all is now a pc gives you far more value for your money. You also get the much better mouse/keyb combo vs crappy fiddly controllers.
And you can look real business like when you carry a laptop, but not so much so when you carry a ps3xbox360wiiiiiiiiiiiiiiiii and a television around with you.
