As far as specific operating versions are concerned, Windows 7 remains a force to be reckoned with at 51.89% of all desktop shares, but Windows 10 has finally unseated Windows XP at the number two spot with an impressive 14.15% market share for the month of March. To put things in perspective, Windows 8 and Windows 8.1 combine for a little under 12% market share having been on the market for over three years. Mac OSX divvies up the remaining share between Linux with version 10.10 taking 2.06% and 10.11 accounting for 4.05% while Linux hangs to its 1.78% influence in the market.
On mobile, Windows accounts for just 2.54% of the operating system pie while iOS takes the second spot with 31.76% and Android hoards the remaining lion share of 60.99%. Investigating the numbers further shows swapping trend in iOS and Android adoption, where iOS has steadily dropped from its 41.55% market share in July of 2015 to just 31.76% as of March 2016 and Android increasing its lead from 51.12% in July 2015 to 60.99% this month. All the while Windows Phone has teetered ever so slightly from 2.60% in August 2015 to 2.54% in March of 2016.
