Well, it's not a bad trade off, I guess. You still have the choice keep some, if not all of your UMD games if you are a retail whore, sell it after registering the game to neutralize somewhat the effect of re-buying the game or just do nothing at all and play your PSP games in your PSP. I guess the disadvantage with the latter there's no improvement whatsoever about gameplay or graphics.
As for me, I've gone digital ever since I've bought my PSP, so no harm done.
