A nice infographic on Android Operating System done by cellphones.org. Among many things it shows you the growth, timeline and market share of the popular mobile OS made by Google. One caveat I noticed (and many others) is the missing Symbian OS in the smartphone market breakdown section shown below in section 3. Symbian has been a powerful and popular OS for smartphones though lately it has been beaten by Android, iPhone and Blackberry.
