Well that and the cell in it. Ps3 was built with too much technology in mind from the get go. Ironically if sony had been more thoughtful about their approach and priced it competitively 360 would definitely not be anywhere near where it is today. The blu-ray drive was expensive but the ideas sony had with it were all wrong with the main stream consumer anyway. Also sony's strategy with consoles has been to push a new disc format. That is what they said on stage at e3. They had cd with ps1. They had dvd with ps2. They had blu-ray with ps3. I highly doubt they will change this approach.

Sony really need to design ps4 to be more like a gaming machine and less like an entertainment device but they won't do that because it is a chance to push stuff in their other divisions as well.

I thought this was I good answer/post so I decided to people should read it twice ^^ What speaks in Nintendo's favor is the fact that MSony have tried to emulate the GamePad in one way or another.
