I am about to call best buy to replace my MGS4 80gb PS3 for a slim. With the replacement i will also be getting $200. Now i am a little upset because i am loosing backwards compatibitlity, 2 usb ports, memory card reader that i actually use, and a nice sleek design. Can someone actually tell me some benefits of owning a slim? Does it have better audio, ports, anything at all? Is it only a downgrade?
