which do you prefer? I like the idea of DD insofar as I will then have many games on my memory card ready to go at any time, but like the DD on the iphone/ipad, etc., they have no resale value. The physical copies can always be resold or traded, which I understand that the gaming companies would like to stop so as to reap as much money as possible from their products, but the DDs are usually more expensive than what I can get new games for, much less for used games. I don't mind paying the low prices for small games on the ipad/iphone, but when games are $30-40, physical copies are often the better value. Of course, saying that, all my PSP games cannot be played on my Vita, since they are all physical copies...
