Smartphone OS Installed Base

communitiesdominatebrands.gifThe indomitable Tomi Ahonen shares some stats from his Phone Book 2012. Of particular interest is the installed base of smartphones, by operating system.

Note that this is the installed base, not recent sales, which means the numbers are more useful for people interested in trying to determine what platforms they should support. Further, they are world numbers which is important as some US-only research, not clearly disclosed as such, tends to be misleading.
