I'm talking about technical people. Why would I care about popularity of Linux if it works for me and may be even better than Windows. It's not a consumer OS for the masses, that's a primary reason of its low popularity, that's correct. I don't agree that part about terminal, I mean, editing registry in Windows is not easier. It's more about investing huge resources into polish and testing, so for most people there are no technical issues which would require complex repairs.
