Most of the stuff at the app store hasn't gotten to the point of limited utility. I think Apple is right. In fact they should be more selective in what goes into the store. When there is so much useless stuff to wade through it discourages one from searching around for the apps that really are useful.
What if David Copperfield decides to sell useless magic apps like whoopie cushion? What if Jerry Seinfeld (who pioneered doing a tv show about nothing) decides to sell an iphone app about nothing?
Well, Seinfeld just signed with Microsoft doing their ads so that chance is slim.
If Jerry Seinfeld makes a iphone app that does nothing except saying the words "yada, yada..." for 99 cents --- a lot of people would buy it. Apple is not going to say no to that kind of easy money. So then it becomes large companies doing useless app is okey, but small developers can't.
