This is the problem. The average user has absolutely no desire to have to know this. It's like expecting people to know how to rewire their house to change a lightbulb, when all they want is to see the hallway. It's great for wireheads who want home brew, home built, tweaked hardware, and ultra-customized systems. But, most people just want to balance the checkbook and surf the net.
I agree. That is why Mac OS X is the first Unix to become popular with the home market. Apple has created a beautiful and easy-to-use graphical interface on top of Unix.
