I am going to have to recant I guess. Quickly looking through the IDC, Gartner, World Bank and Strategy Analytics numbers, I can't find something to cite. If you look at global device shipment numbers from 1996 - 2013 and plot shipments per year with a 5 year tailing use to estimate the user base (which seems the norm for the PC user base values) it seems like 15-20% would be closer to the average, not 10% like I stated. I doubt it's important enough to either of us to spend the time to it. ;)
