I spend less time maintaining linux than Windows 7. I have a dual boot system. I run Debian Stable, all defaults, and it is like a rock.
I saw a report alleging that in Europe, most of the laptops and other computers come loaded with Linux as the primary; people have to buy Microsoft as an add on.
I don’t know if that’s true or not. I also haven’t tried it because: 1) I don’t know how or if it would work with my AVG anti-virus or my No Script and 2) I’m a heavy Word and Excel user.
