I don’t know what the average number is but my guess would be that it’s not very close to hundred. It might even be less than fifty percent.
Having recently acquired an Android phone for dev purposes, I find the UI, built-in controls, installing apps, settings, etc. all completely jarring compared to iPhone.
(Off-topic, I love the Android SDK though, and being able to use Eclipse is great.)
