I'm not sure I follow what you're trying to communicate. It's true that if you only consider an Apple laptop, you will only consider an Apple laptop. Windows laptops compete against each other. Few people cross shop them. That being said, it seems that 75-80% of personal computers sold today are still running Windows, not OS X. As someone that has software that runs equally well on Windows and OS X, and who does not use a track pad, bang for buck on hardware performance and quality (and minimal OEM meddling) sells me my laptop.
It's also true that AMD has an uphill battle with convincing OEMs to make really great laptops using their APUs. But one would suspect that reading this article, you can tell that Asus has at least a foot in the door, as this is a review of a very high quality laptop - the whole package, not just the CPU.
And finally, it's of course also true that most Microsoft Surface products use Intel chips, with just one version of the Surface Laptop using an AMD chip. But they already began to buy into AMD hardware, so I would expect more along those lines this fall!
