The cost of carts for the DS is much cheaper. In fact if the PSP had used carts the cost of producing read only memory would of dropped much faster than the cost of using a propitery disc format.
On the subject I believe itis San disk who is about to release a 5 dollar 1 gigabyte write once SD card and rewritable media for 1 GB isn't much more anyways. I meanI can get a 2gig SD card for 13.95. Since thePSP games are on average more expensive they could of hidden it in the cost and it wouldn't be limited to only 1.8 GBs per game.
A memory card can be very inconvienant for a portable particularily if you have more than one.
The PSP is good system, but really it needed a second analog nub(coded arms was annoying as hell to play). 2 more sholder buttons and IMO a HD to fully realize its potential.
