It also discourages developers from making high-quality apps. If I have to buy 5 different apps for $3 to find the one I like best, I've just given $12 to the developers of apps I'm never going to use again and the best app developer still only gets $3. So where's the incentive for anyone to improve the quality of their apps if they all get paid? This doesn't hold true in cases where there's one clear leader in a category, but I've definitely seen it in more specialized categories or ones with multiple popular titles.

I'd much rather get a free 1-day trial on each of those 5 apps and pay my whole $15 for the one I like best. The problem with this is that it'd kill all the mediocre to lousy app developers, but I just see that as a problem for those developers. It's a win for Apple and consumers, right?
