Other than the CFW/emulation already mentioned, I love that the PSP can be hooked up to a larger screen via component cables, and every single handheld today should support that. My vision is terrible and the fact you can play it on a big screen is awesome. OT I know, but I wish the PSP had been more popular and had gotten the 3d remake of FF4, because despite it being impressive for a DS game, the DS isn't powerful enough to do its art style justice. The Complete collection remake is pretty good but the 3d version with PSP-level graphics would've been SEXY
Have fun with your PSP. Custom FW/easy to find "backup copies" of games, tons of emulation capabilities AND you can play it on a big screen with the 2000-3000. Such an underrated handheld.
