Urg PS3 not immune to crashing

Just went to online account management, change my residential address, entered password.... and it was taking a long time to respond, so I X'd and cancelled. FROZEN. Hmm... guess Sony has been taking some cue's from MS operating systems... On the bright side, the buttons are futuristic, and the unit runs quieter than my powerbook laptop. Its virtually silent. I don't even think it has a fan!
