Just really wanting to be clear here, iOS commands 13.9% of the market, Android has 82.8% (world data = http://www.idc.com/prodserv/smart…). For this and several other reasons, the standard sounds pretty reasonable.

Umm...no. Your data set is for US only. The world is bigger than just our beloved country. World data indicates Android is 82.8% kiddo, Apple iOS is 13.9%. Source http://www.idc.com/prodserv/smart…
