Microsoft claimed last week that it's made '100 million' Windows 8 sales and the claim has been widely repeated. But channel feedback and the experience on the ground point to a very different picture.
The Guardian's Charles Arthur has made a stab at estimating the true figure, and suggests it's much less, at between 57 million and 59 million machines running Redmond's latest OS.
Arthur looks at two metrics of browser usage: StatCounter and Net Applications' NetMarketShare, and extrapolates a usage figure from the number of PCs actually shipped. The logic here is that browser usage is a reliable proxy for real-world usage.
