NetMarketShare's OS market share graph for October 2014.
The seems to be a similarity between MS Windows and Obama-care:
“If you like your operating system (XP), you can keep your operating system”
Interesting distorted chart. It shows Apple Mac OS X.9 at 3.9%, but where are the rest of the Apple Mac OS X listed? Another view of NetMarketShare shows that Apple Mac OS X is 7.05%, LINUX at 1.41% and "Other" which this chart lists at 4.86% is listed at 0%. Hmmmmm. They are hiding all the rest of the OS X usage along with Linux in "Other!"
Let's look at NetMarketShare's October 2014 OS Market Share listing only the major OSes. . . without trying to obfuscate and hide OS X:
Apple is a much higher component of the mix than they show. Here is the chart with the breakdown of what is being hidden under "Other."
Add the 3.16% of other versions of OS X hidden in "Other" and even the second chart is a bit distorted as the total is 7.06% Macs. Incidentally, the actual world market for Macs is now a tad over 10% market share according to actual sales statistics.
