sure mine stuffs up all the time. actually the first one i bought, third time i put a disc in there the disc grabber broke and wouldnt take any more discs in. So i went to eb with my extended warranty and got a new one, no questions of course. So this second one, ever since i got graw2, it sometimes freezes, then when i try to turn it off, the ps button does nothing so i have to hold down the power button on the console for 10 seconds, then it quickly beeps like, 3 or 4 times and it's off. In the past 6 months this has happened like 15 times, with other games now too. There's other little things that happen now too, occasionally it beeps twice quickly when im trying to pull a disc out and the screen freezes for a couple of seconds.
All these sorts of things happen all the time with pc's in my experience so i never really worried about it. As long as i back up my save data im not worried at all, cos a week before my extended warranty runs out, i'm just gonna swap it for a brand new one (hopefully a new model with a larger HDD), re-download all my psn store-bought games, and sync my savedata. Sure I'll lose a few settings and themes etc, but thats not important to me at all
