Questions regarding PSP go
 

I think this just released not long ago. There are not UMD but only the hard drive. Does that mean u can only download the games/music/movies off psn or something ? Does that means games for PSP wont work for the psp go ? Sorry for the silly questions. I am not a gaming person but the new PSP go looks pretty neat.

Correct, the PSP Go only plays downloadable games.

Add $50 and you can own a Playstation 3 instead :lol

Then again, you're not a "gaming person" so there is literally no reason why you should be interested in this.
