Companies want proven systems with a lot of available support/know-how. Employers want systems that don't need much training for new employees (at least on the OS level). Most private customers don't care about user-serviceability and upgradability and aren't interested in learning something new on the OS level - they buy cheap notebooks with Windows or some Chromebooks or even iPads.
