Can open-source overtake the iPhone? The iPad? Apple itself? That's the dominant position of Jim Zemlin, executive director of the Linux Foundation. But is that an idea that's based on reality? He's been trying to paint a connection between Sun and its Solaris OS--a "legacy" operating system to Linux, he suggests--and Apple's various devices. While it's all well and good to somehow consider that just because one mighty empire toppled, the next is just as likely to crack... that's just wrong. Apple has nothing to fear from the open-source world.
