I don't know, I definitely see a price advantage when it comes to Windows computing in general. It isn't because windows computers necessarily loose anything, it's more because they're manufactured on a significantly wider scale and have a greater level of competition among companies that support the Windows platform in some way.

I mean, when you want a MacOS based computer, you are basically stuck with Apple. They essentially have no competition, so they can charge whatever they want for their package. If you want a Windows based computer, there are literally hundreds of manufacturers out there competing for your money (or you can build desktops yourself and save a lot of money there). If anything, it's easier to get a Windows PC with exactly what you want than a Mac.

For example, lets say you want an internal Blu-Ray player/burner on your computer (as I did when I built my computer). With a windows based computer, it's no big deal. Plenty of companies out there are willing to build you a windows based computer to your specs which include a blu-ray player/burner, or you can toss one in and it will work fine. If you buy a mac from Apple, you can't even get an internal blu-ray player (never mind a burner), and even if you buy an external one there are compatibility issues since MacOS technically doesn't support Blu-ray.

Software may be the power behind computers, but software only really allows a computer to do what the hardware can support. If you can't get the hardware you want or need to begin with, then whether or not you can get the software doesn't really matter.
