What is worth to add is the reason why OS threatens M$ just by creating 'tendencies of consumption'. It all comes from a commercially badly chosen starting path:
in reply to OSS and the Profit Motive
At the begining, M$ said that their software was sort of freeware for home users, because their target was the big companies using it. But as time passed, they started restricting more and more its 'popular use', and even the hints that they provided for other companies to build good working software inside their operating system.
They now, trust that they are the only ones that can decide the future of PC users. They need to base on their resources, promotions and not in what is required. This is the end of creative software. They are boring.
They have forgoten what is the mother of all invention. And OS is just what people needs. They reflect what we are missing. So, these times, are going to benefit just LINUX, because of its only OS nature.
