First disappointment: the noise ...
Very quiet in the ignition, the fans start running after a few minutes and even manage to cover the sound of the game! Even the first model of the PS3 did not heat as much.
Second disappointment: playstation network
Free on PS3, you must necessarily subscribe (1 year 50 Playstation Plus) to play network!
Last but no least: PS3 backwards compatibility
Do not expect to play your PS3 games on the PS4 ... she simply does not know how to read!
