What are the major physical differences between the new PS3 Slim and the previous versions of the PS3?
Sony has pretty much crammed the same hardware into a smaller form factor. The new chassis is thinner vertically and horizontally, but it is deeper than the previous PS3 — it’s almost a square. The front power and eject buttons are now keys that can be pressed down (not touch-sensitive), and there’s also no standby power switch on the console’s rear panel.
