> Apple now takes a 15% fee

Surely if there was real competition in the mobile app distribution market, we could see how efficient competitors can be with that 15% or less cut compared to Apple.

> and has a really good review process (updates are reviewed by humans within a day or two)

In this very thread, an iOS developer is lamenting the fact that their iOS app has been held in limbo for weeks by Apple reviewers[1]. It's responsible for 100% of their income, and Apple's arbitrary rules and reviewers are cutting into that.

That doesn't instill confidence in me that Apple has a really good review process at all. To me, it shows that we need real competition in the mobile app distribution space.

This is a fairly rose-colored view. The 15% is recent and applies if you meet a list of conditions, and updates often get stuck just as they would on the Play Store.
