Good for some laughs anyway.
"If, suddenly, Microsoft has a one-in-three chance of losing a desktop PC
sale to Apple, the market will understand that Microsoft no longer
commands complete control of the desktop market. That market is now open
and in flux. It becomes easier for any alternative to play in this
fluctuating market and compete against Microsoft. Linux is the prime
alternative to gain in a fluctuating market, when that market perceives
that Microsoft's momentum is impeded."
Linux is a fine way to get more use out of hardware abandoned by MicroSoft. That's one "market" where the Mac OS will not be a threat to Linux. :') What will happen is, for the few years before Steve Jobs bails on Intel and heads for AMD (or whatever else is around then), Linux use will expand because of the kajillions of machines which will enter the category of unsupported hardware, and there will be more Mac software around.
^^^^^^^^^^^^Linux is a fine way to get more use out of hardware abandoned by MicroSoft.^^^^^^^^^
And hardware abandoned by Apple?
Don't misunderstand, the best thing that can happen is MS losing it's monopoly status. By all means, apple needs to be involved.
Until they are facing competition that's out in the mainstream, things on the spyware/virus front won't get as good as you and I know they should be.
Where Apple on the desktop will help Linux is on the server! if a company is using macs its much easier to integrate everything into Linux backend servers..
