Seems like Windoze maintains its stranglehold (sadly) in the Desktop market. But Android appears to have overtaken IOS in the mobile marketplace in the past couple of years.
Or we have this view (please add the lines for the various Windoze versions):
Fact of the matter is that, despite the JAMF reporting, Apple is still a niche market for the desktop and is losing market share in mobile. I say that with no joy as I am a Linux aficionado, not a Windoze fan. (and as far as I am concerned, any POSIX system is superior to any M$ NT system out there)
Your mobile market share chart is going to more and more meaningless, Mark. It works by measuring ad hits for Advertising that uses NetMarketShare counting software imbedded in the ads on webpages. If you’ll notice the sudden drop in iOS trend line beginning in October 2015 right when Apple started selling large numbers of its new Flagship iPhone 6S and 6S plus, but that makes no sense. However it also coincides with the release of iOS 9, which for the first time enabled AD BLOCKERS on iOS devices which block all ads in Safari and other browsers on iPhones, iPads, etc, which include Ads with NetMarketShare’s counting software. Reports are that upwards of 50% of iOS users downloaded and installed some version of Ad Blocking app.
Since this chart is a percentage chart, the lack of hits being counted for iOS due to the ad blockers will automatically translate as an increase in percentage of illusory hits in the major alternative: Android. In other words, there is no uptick in market share in Android shown on this chart, only a sudden drop in ads being counted on iOS devices, making it seem that there are fewer iOS devices on the Internet when that is not the case.
