I can say the exact same about windows. It's confusing as hell, a mishmash of weird semi-trustable drivers and utilities with no overall plan.

For a casual user it's impossible without google to figure out how to change simple settings like making alt-tab stop being on crack and disappear after 0.5 seconds of indecision. Or figure out why plugging in a headphone requires a confirmation on some machines, but not on others... Etc.
