Probably because the PS3 != Mac
Cant believe people still use a PS3....its all about the Xbox - the 1 thing MS got right!
(for the record, I own both but as you probably guessed, dislike the PS3)
Right... I can't think of a single device with a higher return rate due to product failure and the people still keep buying them. The device is garbage since it came it out. As far as hardware is concerned, the PS3 blows it out of the water. I am not talking just RAM, CPU, and GPU, I am talking to the entire experience from built-in USB rechargeable controllers, a hard drive, bluray, internet browser, bluetooth, and wifi right out of the box. These are things that can't all be said about the various version of the 360 over time.
I don't know a single person who actually plays their 360, that hasn't sent one back. I don't buy products that are inevitably going to fail before the technology itself is obsolete.
