Although true, this is seemingly biased as Android usage spans a plethora of phones whereas the iPhone is a singular phone on a singular carrier. It's a very tough comparison to make. This would be similar to comparing the number of copies of a single book being sold under one publisher to the entirety of O'Reilly book sales. Kudos for even coming close.
Side note: I do not own a single mac product. No biases.
