Wikimedia just posted more usage statistics. Windows had a 49.93% share in August of 2013. 4 years ago, for the month of September 2009, 88.68% of Wikimedia users used Windows PCs.
In 4 years, Microsoft dropped from stably controlling nearly 90% of the OS market for hosts used to browse the web, to controlling less than half , and dropping steadily. For the last 12 months, Microsoft's market share has been dropping on average more than 1.5% per month
Sentiment: Strong Sell
Well, this could also mean that the typical wikipedia lookup is done more on the phone, than going to the computer to do the lookup. This would mean a drastic drop in wikipedia visits from windows desktops, but doesn't necessarily mean a huge drop in windows desktop market share. Although there is a drop.
