Yes, you're right. My preceding comment ignores the shift from dumb to smartphones. But seriously, read what I wrote in the post. This internal shift of mix between smartphones and dumbphones, or the rise of many Android manufacturers who aren't in the top 5 (e.g. HTC) is exactly the point. I wonder whether the intent of the "switchers" from dumbphone to smartphones all have the same intent to run apps. I also noted and amplified the rapid Android share growth using the same "mathematical trick" you mention.
