Oh, you mean like how Microsoft bundles Office with it's distro? You know, the one they call
Windows.
I can see an argument being made that people don't want an "operating system", they want a computer. And when most people say computer, they don't mean the box. That's what geeks say. When an average person says computer, they mean all the applications, peripherals, internet access, etc., that all gets packed into the magic box.
Linux and its supporters have never quite managed to grasp the Magic Box school of thought. Until they do, they'll never be a competitor. This is a cultural problem, not a technological one. Look at Apple. First we ignored them, then we laughed at them, then somehow, overnight, OS X became a contender and Apple became a massive corporation. How did that happen?
Hint: Apple doesn't sell 'operating systems' or 'ipads' or whatever. They are selling an experience. And if you ask the average person what the Linux experience is... they'll look at you, facepalm, and say flatly "I couldn't get the damn thing to work."
Linux vendors need to sell an experience, not a product. It needs to be well-supported, preconfigured with everything the average person wants on a computer (or whoever their target demographic is... IT managers, server lackies, whatever...), so all they do is push the button and there it is. It. Just. F*cking. Works.
