Linux will become ubiquitous in the year 3000. Okay, that was a horrible joke. Linux is just a kernel, the engine that runs an operating system. By itself, it is essentially useless. Kernels shouldn't be discussed or noticed by normal users. And as such when providing these users with reviews, previews and "professional" opinions, computer consultants, computer reviewers and computer journalists should not spew headlines like "Linux is not ready for prime time", "Linux on the desktop by XXX", "Linux to takeover Windows", "Linux is not ready for desktop" and so on.
How did Apple manage to create OS X to be so easy, so pretty, so stable and all in such a short time?
Because a significant chunk of the work was already done for them. OS X is an evolution of NeXT, which was around a long time ago.
