Although the Slim is a good buy at a cheap price, i personally hate it. Original PS3 has much better finishing along with glossy coat over the surface. The PS3 which my bro has is the 60GB one which was very rare and out for a limited time, it includes the features of 4 USB ports, backwards compatibilty and different expansion slots. Backwards compatibility is the feature where PS1 and PS2 games can work on the PS3 and it is indeed a very useful feature which is not available in any of the PS3 models nowadays whether slim or not.
