Moving to Linux used to be a big deal. Sure, it was cheaper, more reliable and more flexible — but who did you turn to when things went wrong? In an enterprise world that had grown up with the idea that Unix needed to be complex and expensive — and that Windows was a quick-and-dirty plan B — the idea of getting a robust, scalable operating system for free just didn't click for many years.
