Ed Bott: There is never a shortage of Apple-versus-Microsoft yammering in the blogosphere, but I haven’t seen much in the way of actual data. Is Apple really making a dent in Microsoft’s long-standing Windows monopoly? Are mobile devices like the iPhone and iPad taking over tasks that used to be done by PCs? Sales figures tell part of the story, but in my opinion the best data comes from analyzing how devices are being used in the real world. I went off in search of hard numbers, and I found them at the same source I used earlier this year to measure Windows 7 adoption rates (see When will XP finally fade away?)…
