Also, the comparison of Android to Windows breaks down when you look at smartphone profit share. Unlike Windows, OEMs don't pay to license AOSP or GMS. While Google monetizes GMS through mobile advertising in their apps, the majority of the profits in the industry are from hardware sales/carrier subsidies (unlike the PC business which is mostly a commodity business). That is to say that most of the profits on "Android" are captured by companies like Samsung, HTC, and Amazon.
