Tim O'Reilly, famed publisher of "open source" and free (GNU) software books, has been looking at X Switchers. He doesn't claim this is any sort of scientific survey, of course, and the sample is tiny, but the anecodotal evidence is interesting. Basically, he thinks Apple's Mac OS X is proving more appealing to Linux users (who want Unix and something that "just works") than Mac OS 9 or Windows users. His conclusion (including a pinch of salt): "Apple may be wise to target Unix/Linux rather than Windows in their switch campaign." Although the Macintosh "topping" is closed and proprietary, the underlying operating system in OS X is based on BSD Unix and is available in a Free Software Foundaton distribution, GNU-Darwin, that also runs on Intel processors. The amusing thing about this development is the possibility that people who now use the GNU (Gnu's Not Unix) operating system with a Linux kernel (wrongly calling the whole thing "Linux") will be able to switch to a GNU operating system without Linux.
