40hz, that's a very well-written response to the topic & very logical. Unfortunately, people are not logical creatures. Once you take away all the people who are actually interested in technology for technology's sake, a person's tendency towards using an OS is going to really boil down to inertia. The only questions they really ask themselves are "What do we use at work?", "What do my friends use?", and "Which choice will yield me the most people I can ask when I can't figure something out?"
What they need and what's usable really doesn't factor into the decision process. Articles like the one in the OP with the theme of person with small amount of notoriety made the switch to <product/OS> and here's what happened either falls on ears (eyes?) that don't care either do to reasons I've listed above or they don't care because they are actually tech-savvy enough to do their own research rather than spend time listening to a talking head who is getting paid for his words and therefore his level of objectivity is unknown.
