What is the primary focus of Linux development. Performance was undoubtedly what Torvalds had in mind. Guided by the dreams of 'World domination', becoming an easy to use desktop operating system with windows like GUI / Ease of Use/ Hardware Autodection etc. top the wishlist today.
Which makes me wonder, whether there is going to be a time, when Windows itself would be history, & linux would be the de facto standard. That would be the time when we would see FreeBSD/NetBSD/OpenBSD emerging as alternatives, and people arguing why the *BSD's are superior to Linux, in terms of security. Others who are not so paranoid about security may be arguing why Linux isn't as free as the Hurd. And of course the dedicated band of followers of Apple's Macs would still be around, arguing why Mac still beats them all.
