I know less than nothing about UNIX, but is Apple's obsession with full UNIX certification and ZFS a sign that it is not seeking world domination and to be the next MS (by releasing OS X for all x86 computers), but is instead seeking to be a part of the UNIX/Linux ecosystem, able to offer its software on other distros (is that the right word?) with minimum recoding? This it seems to me would guarantee the sort of longevity that I think Apple is interested in. Because if it simply replaces MS, then eventually UNIX/Linux will inevitably overtake. And I think rather than being an evolutionary stepping-stone, Apple wants to be a survivor that keeps going and going for as long as possible - this is its aim along with innovation above and beyond pure money making. Does this make sense? I don't think that by their nature they are an all or nothing company. If the tech world changes to Solaris, Ubuntu, OS X, etc. being the dominant players, there will still be money just not the kind that MS is used to. MS is an all or nothing Vegas or bust kind of outfit that looks at the current climate and like a big gorilla scratches its head, because it hasn't a clue what is going on or why its loyal consumers are fleeing like rats on a sinking ship.
