Perhaps I am just dense, but the article references, specifically, the "Pro" market. For most pros that I know (and I am among them), our OS choice is often based on our tools, not the other way around. If I need Photoshop, Lightroom, Logic Pro, Visual Studio, etc., switching will be quite a chore. For the average user, this is probably a much more appealing argument.
