Well from what I can tell, it's totally worth it if you like handheld gaming. The battery life is mediocre (5-7 hours per charge), the launch titles are pretty awesome in my opinion, and from what I can tell there are no issues with the hardware (and the supposed errors it's been said to have are almost nothing.)
If you can afford it and you liked the PSP at all, get this. seriously.
