It's marketing. Microsoft can afford to go up to a company and say "I'll give you $40 for every computer you include windows with". I'm sure they don't say that exactly, but the manufacturers/resellers do get profits from putting Windows on a computer. The linux community can't afford to do that, and it's not the point of linux anyways. Because linux is free, they can't get a profit from putting it on a computer (unless of course they charge extra to have linux on there, rather than no os[because microsoft tends to not allow oems to have another OS offered then theirs]) If linux were to never be free, to be worth easily $400, it would be included on many computers, because it's easier to get a profit for something that costs more. For instance, I sell a car for $27,000... i buy it for $20,000 though. there's $7,000. i get a pinto for $400, sell it for $600... that's $200. what costs more gives more profits, what gives more profits gets sold. Ignorance would be the reason why people don't use linux. They don't know it exists, and those that do tend to think "if it's so great then why isn't it coming on computers like windows is?".
well i'm done. I have to go, later.
