We’ve been matching up popular web services, applications and mobile apps against each other in heated one-on-one battles here in our weekly Faceoff Series. Last week Microsoft Office bested Google Docs in a head to head race for the title of office suite champion.

This week we turned our attention to a rather timely battle being waged on the mobile front, between Apple’s still wildly-selling iPhone platform and Google’s slower to boil Android mobile operating system. Apparently the latter has been gaining some ground, resulting in our first unexpected upset victory in the Faceoff series.

… Google Android is the winning platform by a more than 2:1 margin. Out of 5045 total votes, Android walked away with 3323 of them or 66%, while the iPhone platform only netted 1494 or 30%. The tie vote included 228 or 5% who just couldn’t choose between them. Many people cited the openness of the platform and third-party development process as well as Android’s versatility, being able to be put to use not just on phones but also netbooks, tablet devices, eReaders and more.

Still, given the popularity of the iPhone we were a little surprised by these results. Are you? Let us know in the comments.
