I disagree - android apps are more difficult to polish then iPhone apps, for a variety of reasons. * Bad defaults. (For example, on Android your app will look like crap if you have any gradients, unless you make sure to change the window format to PixelFormat.RGBA_8888 at startup). * Core UI components are ugly and behave poorly * Sluggish performance due to lack of hardware accelerated GUI (especially visible during animations, scrolling, etc) * Extra work to support a variety of screen sizes and input methods (trackball, etc) * Using custom-drawn components on Android that need animation (e.g. SurfaceView) results in inescapable flickering and compositing glitches - and you certainly can't use them properly with transitions. Popular iPhone apps tend to have a lot of UI candy, so this makes it harder to compete.
