I have been a full-time Linux use for over a decade, running Linux desktop on all my machines. But there is a reason for the year of Linux desktop not coming: it is garbage. Horrible defaults everywhere, every customization is hidden in some totally unexpected place, bad error handling, driver quality all over the place...

Learning Linux as a user and developer made my career, but I use it at home just out of spite (I feel a special hate towards MS), and not because it is such a great experience.
