What is the chart measuring? The article implies that it represents App Store visits. Do they buy anything, though? That's the metric that's important to developers.
That's the tricky thing. As far as I can tell, the graph shows what percentage of phone users (or mobile Internet users?) regularly access the stores.
Basically, it suggests that about 9% of app users have iPhones in China (which still seems very high -- but I guess they're all in affluent areas), 13% have Android phones, and the rest have Symbian/Nokia phones (65%ish).
This article[1] suggests that the Ovi store gets 2.7 million app downloads a day. The Apple App store gets 17 million app downloads a day with less than half the marketshare.
Agreed. There is obviously a huge Nokia/Symbian user base, but it would be interesting to learn more about the demographics/buying habits/Internet-usage habits for those users. If many of them are in rural or developing areas, their ISP may only offer a capped bandwidth plan which may cause them to shy away from using data-intensive apps, or they may just not be as motivated to use some apps that ultimately lead to revenue generation (either directly through app purchases or down the line via upgrades or services that compliment the initial app download).
