The point of "Linux on the desktop" was not that it happens for you and the other commenter, but that Linux becomes mainstream. :) Never happened and unless something extraordinary occurs it likely never will. And Android doesn't count, obviously.
True. But it also has the connotation that Linux is "not good enough" for the desktop, and this is false. Popularity has a lot of factors, sadly. A user-friendly Linux like Ubuntu is indeed "good enough" and has been so for years.
