John Voorhees has a good section in his article about the Apple antitrust lawsuit and relevant market. I wish the case was more focused on the App Store, because from a dev perspective the market is really people who buy phones and apps. Apple dominates that.
Mike Wolfinbarger @manton Dominates? Based on 15 years of direct experience, at best they are a little over half the market for phones and about two-thirds of the market for apps in the US. Less elsewhere.
Mike Wolfinbarger @manton And if Apple were a lower percentage of either of those, my revenue would be lower, not higher.
