"The relevant market consists of a 'catalogue' of goods and/or services which are considered substitutes by the customer. Such a catalogue is considered 'worth monopolising' if should only one single supplier provided it, that supplier could profitably increase its price without its customers turning away and choosing other goods and services from other suppliers."
So the question is this: if Apple were to increase its share of revenue by 5% to 10%, would developers move to Android, BlackBerry, or WP7? Absolutely. Even at the current level, there is plenty of cross-over between Android and iOS applications. In antitrust terms, the AppStore is not a market.
