I don't mind with downloadable games on the PC since those
a) are always readily available. There's no limited supply.
b) get as cheap as used games after having been out for a while, thanks to publishers trying to squeeze out every last cent from the game.
c) can always be easily obtained elsewhere if they, for some reason, are made no longer available.
Only one of those things has been true for consoles and downloadable games, though. I rarely see companies drop prices on XBLA games, and if they get taken off the store, or if they can't be used on the next console for some reason and something happens to your hard drive, there's no easy way to ever play them again.
