Those numbers just don't add up. If you have 7.8 million iPad users in the US and there is
over 100 million smartphone users in the US, this still doesn't account for the 20% difference even when you assume that there are no Android tablet users.
37.9 million iOS users (Apple has 30.2% in this thread's smartphone statistic)
23.8 million Android users (Google has 50.1% in this thread's smartphone statistic)
The iPad statistic fits nearly perfectly with the smartphone statistic, while the Android statistic does not even account for half of the number of Android smartphone users.
Somethings wrong here, don't you think?
