The only game console/platform I've ever owned since having an Atari 2600 as a teenager is a Playstation 3. I bought it as a blu-ray player, tried a few demos, and 4+ years and 75+ games later, I guess I'm now a "gamer."
As I posted in another thread, I am probably done buying games for my PS3. Mandatory installs, patches and notoriously slow PSN download speeds mean it can be hours before you can play your game.
I have all the modern consoles and mainly I use the 360 but recently Ive had a resurgence in pc gaming since I upgraded to an i5 2500k and added a gtx 460 card.
