The sleep mode on the psp works very much in the same way as hibernation mode works on a laptop, Where it writes the contents of memory to the hard drive/nand flash/sd card.
Scenario:
Your playing a game or watching a movie etc and you have to go to the toilet, Or mum call for you to go and have a bath/shower, Or anything for that matter that breaks you away from what you are doing on the psp, Or maybe you need to change batteries. What do you do ?, Remember where you got upto in the film you where watching or go to the menu in the emulator or game and create a saved game/state (If that is even supported at that particular part of the game), Or loose everything upto that point. Or do you shove the psp into standby/hibernation mode so you can continue EXACTLY where you left off.
I know which i would prefer.
Excuse the over use of the word OR. :rolleyes:
