Trust them, that is another matter... I'm referring to their technology which is not half as bad as many people seem to think. Yes they're monopolists, are they not all ? Or aspiring to be ? They do, at last, make a honest effort to listen to their users. I still prefer the Microsoft monopoly to the anarchy of Linux, of which there are at least 3 or 4 dozen different versions, and where you have to rely on some happy hacker to fix your problem.
Linux was never really meant for the ordinary user. However, Ubuntu is a step in the right direction on that front.
Mac OS X is the better operating system for the ordinary user for several reasons. Primarily, it has a nice interface. And under the surface it is BSD Unix. And Unix >>>> Windows any day of the week.
