PSP essential questions for a noob like me!?

okay, it has a 3.5 mm jak. no it has no bluetooth. it has wi-fi(WLAN or Wireles internet) you don't need to do all that stupid stuff people go talking around. yes, you can put music on it. Many formats, movies too, yes. battery life is ok but could be better. a loudspeaker (normal, nothing gr8) and it is cool. games are costly but its fine.
