I would describe myself as firmly "in the middle", and I honestly don't disagree with your points overall. However, I think Windows isn't really "easier to use" than most Linux distros, it's just what most people are used to.
That doesn't take away from your argument, as being familiar with an OS will make it easier to use and that's completely valid, but someone who's used Linux all their life would similarly face struggles using Windows. User inertia is a huge factor contributing to Windows' marketshare.
