So in other words, just like most "switched from X to Y" stories: it depends on a lot of factors and there is no one-size-fits-all. In this specific case however, the issue is much easier: author wanted a collection of components, not a packaged experience. So in other words: if the device is the goal (or having a collection of components), you might not enjoy an Apple product. If you want a specific experience, then…
I thought the basic summary at the end said a lot: "I wanted a cheap travel laptop I could replace without blinking an eye at the price."
But from the general comments you can glean that people still seem to think in terms of "one has to be absolutely better than the other". At best one could argue that the mass-market enjoys one thing more than the other, but even that depends on where you are located in the world and what skills you have. Sometimes I wonder what would have happened if the OLPC project had a western version where kids start out with one of those, that would make both cases even clearer (i.e. some would not enjoy doing work 'for' the device instead of doing work 'with' the device).
