Nope, You can't compete with Apple. "Apple rejected iPad app for using pinch to expand gesture" - http://www.appleinsider.com/article...
Apple continually shows it's true colors through the App Store. This is the main reason that I prefer Android over iPhone. This is also the main reason that I will wait for something running a Google OS for a tablet. I feel that I'm better off being able to decide for myself what software should, could, and will run on my device. I also feel that the App Store promotes an atmosphere of non-competition, and unfair competition. That can't be good for consumers. I do understand, however, why the App Store experience may be preferable to some people. Less to think about, or worry about, when installing software makes for great usability. I also think that we'll see more and more movement to developers building native Android apps and then porting to iPhoneOS. Already we're starting to see that. - guruvan (Rob Nelson)
