If you are a user of an iPhone you cannot get an app from elsewhere. If I develop an app and sell if for $4.99 on the app store (price based on projections of downloads, how much apple takes, etc needed to make my money back). However I could offer the same app for $3.99 on an appstore that took a more reasonable percentage cut and get more downloads since lots of users are price sensitive. From this perspective, it looks like a textbook case where prices are higher for consumers due to the lack of competition. Even if one builds for the web, apple only allows a single browser engine which is their own. They unilaterally can decide what to implement and what features to add or remove.
