You had me. You really did - until you mentioned, "but when you look at just how much hardware they support, and how well it works, ". While I agree that most, if not all hardware is designed to work and has drivers for windows, it is not Microsoft that is doing the 'supporting'. How much of that hardware would automatically install, activate, and provide every feature designed if it weren't for the drivers from the OEM. Why do you think all those printers, mice, cameras, biometrics, etc... come with a CD? The OEMs decide what to support, and they typically choose the most widely used. It used to be that everything came with a "designed for Windows" logo, even though they provided their own drivers and supporting software. You now see Mac logos included as well and rarely you see all three MS, Mac, and Linux.
