Two of my favorite games at the moment use consumable IAPs, and I think it they have a good model. Real Racing 3, and Trials Frontier both offer consumable IAPs that mostly remove waiting, or a boring portion of the gameplay. One can compete in game to earn the same money, and wait for repairs... or they can spend money and keep playing. So far I have not spent any money on these games (I am not a good target market for much of anything, so don't read too much into me playing free games), but I enjoy them a lot, and the developers are making a decent business out of it. Consumable IPAs give developers a chance to get as much money as possible from each person playing. From me that might be $0, but many people are likely to spend more than the $4.99 that would otherwise be the target app price. This seems like the ideal business model to me.
