Sony Playstation 3

Sony’s PlayStation 3 is a gaming giant -- figuratively and literally. Figuratively, its graphics are amazing and it has been praised as the best Blu-ray player you can buy. Literally, the 80GB system weighs more than 11 pounds and sucks five times as much energy as a fridge when running, according to a 2008 study. The just-announced PS3 Slim kicks those beastly qualities to the curb.

After Microsoft's announcement at the E3 conference of Project Natal, Sony unveiled its own version of motion-capture gaming, both playing catch-up to Nintendo's Wii. Using the Playstation Eye camera and a colorfully globe-tipped controller, the new hardware claims to allow true 1:1 motion response.
