Yep, that includes iOS.
A new survey from Gartner, who previously predicted that Apple would reign supreme until 2015, has revealed the Android has taken 62% of the tablet OS market share.
What helped Google’s OS is their wide range of tablet options: more affordable, smaller screen Android tablets means more sales. Google’s own Nexus line of tablets probably help account for many of these sales.
Samsung’s tablet market share exploded with a 336% growth in market share, accounting for 19.1% of all tablet sales and making them the number one Android tablet manufacturer.
Apple has 36% of all the tablet market share, leaving Windows tablets to only account for 2.1%.
