Why are people that couldn't give a shit about the PS3's aesthetics even in this topic, this whole topic is about what it may look like. If you don't give a shit and never look at your PS3, then be happy with your PS3 fatty edition and don't worry about this topic. I suppose the other important factor may be lower price, but if you are a current PS3 owner, that really shouldn't affect you anyway..
Personally I'm not hung up on the looks of a console, but there is some importance. If you have regular guests over, and I mean the kind that making a halfway decent impression is important, you don't want some tacky Fisher Price looking shit in your living room.
