I could understand any other console or new Android handheld but PSP has to be the second most miserable console to go back to. Barrel jack charger, some of the worse sticks ever made, and infamous battery bloating. The only worse choice is the Game Gear.

A used Vita would be a good modern replacement (and not even that much more expensive) but even in their afterlife I guess it's still doomed to play second fiddle to PSP.
