I suggest waiting for the new PSP that was featured at E3 it has like a flip out control thing, I think it doesn't have a UMD drive either. Its only a matter of time before they can hack that too.
But I fucking hate Sony why are they trying to hard to prevent custom firmwire. I have an old phat PSP with CFW on it, I got quake 1 and MGSPO+ on my Memory Stick.
