I generally agree, but it seems like it could have some bad side-effects if it becomes a popular business model, though.

There are a handful of interesting paid apps that are very short, unique experiences - which don't try to drag out the game to keep you playing it every day for months.

Its already getting harder and harder to actually sell/buy apps for money upfront, and this seems like it will make it even harder. And while I seem to be in a tiny minority of 'app' consumers, that is still my preferred method of obtaining new applications.
