The most common trap here is the early iOS app which gets some buzz. All of a sudden, the founders hear “When are you building for Android?” The natural, enthusiastic response to sincere requests of the Android chorus is to go ahead and build for Android and seek more downloads, more growth, more revenue. I have a different view though. The proper response is: “No. Buy an iPhone.”

...

  1. Early-stage startup teams cannot afford to handle the hardware fragmentation that plagues Android.
  2. Study after study demonstrates iOS users are not only growing in key geographies, but are more valuable customers.
  3. iPhone 5c and future low cost models will likely steal share from Android relative to yesterday.

I agree with #1 above but I'm not sure about #3.
