Really, I've gotta ask, _is_ there a market for alternatives?
Well, ok then -- if you can't succeed unless your OS is perfectly bug-free, feature-complete, and pleasant to use, then yeah, only mega-corps will ever succeed, because only a mega-corp can manage that kind of trick upon the initial release of an OS.
being open just doesn't pay (in every sense of that term).
A Brit, a Frenchman and a Russian are viewing a painting of Adam and Eve frolicking in the Garden of Eden. "Look at their reserve, their calm," muses the Brit. "They must be British." "Nonsense," the Frenchman disagrees. "They're naked, and so beautiful. Clearly, they are French." "No clothes, no shelter," the Russian points out, "they have only an apple to eat, and they're being told this is paradise. They are certainly Russian."
there is no hope for smaller players.
