I've been looking at multiple data sets lately, all of them interesting, all of them offering an imperfect glimpse of one part of a very large installed base. But in total, they tell a fascinating story about the trajectory of traditional (desktop and laptop) computing.

Actually, make that three stories, because with an installed base of 1.5 billion PCs, the picture is far too complicated to be reduced to a single bar chart (although that's what seems to happen to the tech media on the first day of each month, when analytics companies do their data dumps for the previous month).

For this story, I've gathered the latest data, covering the entire month of January 2016, from Net Market Share, StatCounter Global Stats, and the United States Government's Digital Analytics Program (DAP).
