[quote name='jer7583']TV out is the only main feature. If you use custom firmware I'd say it's not worth sacrificing playing ISOs, for TV-out. ripping your UMDs and PSOne discs to the memory card will almost double the battery life vs playing off UMD, remove almost all loading delays, and the 333mHZ mode smooths out the framerate on lots of 3D games.
The new PSP will only do 333 on new games, not older games, and who knows if it'll have a new motherboard that can't be cracked for custom firmware for ages? Wait and see.[/QUOTE]For people like me that feel custom firmware is wrong, I'm very glad the new PSP has double the ram, so games won't have to access the UMD much (to shorten load times). Also, I play a lot of fighters and the PSP D-pad is terrible for them. The redesigned PSP had a d-pad a lot like the PS3 one, which is excellent.
