This looks rather interesting. Assuming it's not too pricey when it launches, I'm willing to bet this becomes the next cool underground toy. Sure, your v1.50 PSP could do the same, but Sony appears to be actively trying to push it's hackability out of the limelight. This GPX2 on the other hand is all about you putting your own stuff on it and having no official game platform. Seems like a winner to me.
