Bill Gates: Unplugged |CNET.com: "So at the end of the day it's the Unix guys who are feeling the greater impact of Linux's adoption?
Remember, there are hundreds of incompatible versions of Linux. The fact that we call it Linux hides the fact that this driver works on this version, and this app works on that version. But there is a world where you don't test for binary compatibility because you don't have testers. It's just a different world than ours. That approach has certain benefits and advantages in terms of the way things get put together and ours has certain benefits and advantages. It's the primary operating system we'll be competing against.
Five years ago it would have been Windows versus OS/2. A few years before, it would have been Windows versus Macintosh. Before, maybe it would have been C/PM 86, and before that, maybe CP/M 80. There's always been some challenger to the operating system. Linux--which is only a kernel--is not where the interesting stuff is going on nowadays."
