I agree. The "make an iPad app" camps have a very narrow focus and appeal. Are we really changing the world with an iPad app? I just had a cursory glance at the website and saw one kid claim that he wanted to build an autonomous go-kart. Goals like that are exciting and interesting. Even if he fails at that he will learn a lot of useful skills. An iPad app, no matter how widely adopted it is not going to change the world.
