Mac OS X could put the squeeze on Linux.

…Linux recently got a new round of thrashing from another competitor to Linux on the desktop: Mac OS X. How so? At its core Mac OS X runs a version of Unix called BSD (Berkeley Standard Distribution). Linux is, of course, also based on the Unix tradition. According to ComputerUser this means that Mac OS X and Linux could appeal to many of the same users.

That’s the way that I see it. OSX gives UNIX what it’s needed for a long time: a fully integrated desktop environment with millions of users and thousands of commercial applications.

Perhaps the open source Linux guys should consider working on the Darwin code base?
