I'm really agree about that a lot off xbox 360 user move to PS3. The only reason that i know that they still hold on 360 only because it can be modded.
Most of them complaining about over heat on 360 still unresolved. 360 is very sensitive especially the DVD drive, it can scratch the dvd so easily if the dvd drive get error.
On Ps3 the over heat problem that i seem so far only happened on some series only. There is a small chance to scratch a bluray disc even your BD drive get error almost impossible if you didn't mess up inside the BD drive.
On Ps3 most of people didn't choose it because the PS3 is too expensive from the beginning and now they still cannot be modded and the game it self is too expensive especially new title.
So basically if you want to play a good and safe console i suggest you to choose PS3, if you want to play a cheaper one then choose 360 because it can be piracy.
