I got one :)
had mine since they came out in Japan last December, i mainly played ridge racers and mercury on mine, got a big memory card in it and use it for playing old skool games via emulators like megadrive and snes games :)
also been playing that old spectrum classic "Bruce Lee" on the psp ahhh memories :)
im looking forward to Gran turismo. and Aido is right about Sony restricting the speed of the console, they have made the games stick to 222 mhz for a longer battery life, the guys making the emulators and home made programs have the option to run the machine at full speed or 333 mhz but it saps the battery in about 2 hours, Guess sony need to bring out a super battery before commercial games come out using the 333 speed, My guess is Gran Turismo will need the high speed option.
but over all a Great Machine, but the nintendo DS has better games in my opinion and much more originallity.
