My review

PS3 = enjoy Sony Exclusive games like God of War, Resistance, etc. however Strong security on piracy. Phat versions likely gets the YLOD, buy slim instead

XBOX360 = RROD on phat versions. microsoft games like gears of war. Easy to hack for downloadable games

PSVITA = portable evolution, a must buy. however.. just wait for a couple of years to until it cuts its price, has many Major games worth buying, or modded by the hacking community

PC = undying
