Christ, that's expensive. Absolute no from me. Can get the same thing online for free, etc.
Devices running iOS aren't games consoles. They have the ability to play games but they're a totally different market from Nintendo's handheld consoles; not competition imo. Also, the application wasn't even made by Nintendo. It was made by The Pokémon Company, according to the App Store, so Nintendo wouldn't have any real say in the matter even if iOS devices were competition.
