Sometimes the data is hard to explain logically when it comes to which OS is winning mindshare...
On the one hand, it's pretty well accepted that Android is pushing 75% of mobile OS marketshare while iOS is somewhat South of 20%. In the US the numbers are slightly better for iOS where it makes up around 35% of all devices. Now, data that shows usage typically tends to favor iOS. The reason put forth is that many Android phones are little more than feature phones and get used as such and that explains major usage statistics. However, how could that hold for the US, where the flagship Android phones tend to sell the best. The difference between platforms as per IBM's study is almost staggering given their respective market shares.
The one explanation for the above to be true is that Apple tends to actually sell a higher percentage of
what they ship (saying this since sales volumes that are reported are usually shipped). After all, shipped
units of just the Galaxy S4 v. iPhone seems very close and Android tablets are according to IDC
outselling iOS tablets 2:1. So what do you think is going on?
