But it is strikingly clear that Apple and Linux aren't fighting for the same set of market. On June 6, 2006, the first x86-based Mac comes out – after general interests dies down, Macs would be no different from the marketing standpoint then as it would now.
Macs would still be a niche market. Apple Senior Vice President Phil Schiller confirmed, "We will not allow running Mac OS X on anything other than an Apple Mac." Nothing has change. In fact, the sole Apple advantage gained by moving to an Intel-based platform is that new users could use Windows along with Mac OS X – however Schiller also confirmed that Apple wouldn't sell nor support Windows on their Macs.
As such, Mac OS X would continue to be doomed to be the operating system for a shrinking, in terms of market share, market. Unlike Linux, it is unlikely much corporations would mass-deploy Macs starting June 6, 2005 for non-design related uses. Hardly anyone that wouldn't forking out for today's Macs would fork out for Macs next year. Having a better user interface than Linux would make not much of a difference.
Could Apple gain more market share for Mac OS X? Perhaps. But it wouldn't be by the virtue of changing platforms. They could start stealing market share from Microsoft should they start licensing out Mac OS X to non-Apple hardware. But they could already have done that with on the PowerPC platform. In fact, by licensing Mac OS X licenses out, it could perhaps have 'saved' PowerPC in the sense that IBM and Freescale have more of a market and economic reason to churn out better and faster processors.
But of course, in such a scenario, Apple's profit would be severely undermined, and that's why it is unlikely Mac OS X would be sold for non-Apple hardware and thus be an actual threat to Microsoft Windows anytime soon, be it on PowerPC or Pentium. And because of that, desktop Linux developers need not worry that Linux would be pushed off the market.
