ganesh: I get that argument, but Apple's solution ("free should be free") only makes the matter WORSE. See [1]; in short, say you download a free app, and you find out it's basically useless without making in-app purchases. Okay, annoying, but you've lost nothing. With the current situation, you've *paid* and downloaded for an app, *and* you find out it's useless without in-app purchases. Now you've lost money, and you're mighty pissed. How is this situation in any way better than had the app been free? It's already happening, see [2].

Re the "Try before you buy" (aka shareware) alternative: Devs have been asking for this since day one, but apparently it's nothing Apple cares for.
