PSP currently available here in Nokami land, land of Geisha and sushi. On sale at around 20000yen (two hundred dollars or so I guess or 100 pound). Has anyone got one? If so, what are your impressions of it? Advantages and/or disadvantages? I've heard one possible prob is battery life, another is an easily scratchable screen. Probably more advantages than disadvantages though. How does it compare to the DS? I haven't got mine yet but I'm getting it for Christmas . My first game will be Metal Gear Acid.
