i was playing it at eb yesterday. Its pretty nice, graphics are ok. buttons feel nice and the the touchpad has its advantages. I really liked the messaging feature they added. you can draw anything on there and send it wirelessly
PSP is gonna blow. The battery lasts Approximently 3 hours and the game selection si icky. It's huge, worthless, and not very cool. Sony admitted that they are loosing money on them because of how much it costs to make them. Plus it dosent have WiFi or Bluetooth like DS does.
