I've had one app in the App Store since its launch and admittedly only do hobbyist work now and it doesn't bother me at all. I bought a Mac and learned Objective-C just to make stuff for my iPhone and I learned to really like Xcode and Obj-C.

I can understand why developers want their work on as many platforms as possible but when each platform has distinct interaction and design paradigms they can't fulfill them as well as they should by targeting the least common denominator.
