Our experience supporting both iOS and Android versions of our app for 18 months (>1M daily users) is that Android users are much less satisfied. We are twice as likely to get a support request from an Android user and those requests tend to be more complex (and qualitatively more grumpy). For example, take push notifications. C2DM only works on 2.2 devices with a logged-in Google account, so you need a fall back push mechanism. Even with C2DM you must struggle with various challenges surrounding power management and wifi sleep. In comparison, APNS just works. Also, Android aggressively deprecates. With ICS there's a brand new Fragments API, which to be sure has a backward compatibility library, but now you are faced with the choice of rewriting your app to fit the new UI style (and potentially confusing existing users), limping along with the old Android styles, or supporting both and making your life miserable. Hey, and don't forget landscape mode and multiple aspect ratios! I could go on, but I'm getting negative.
