Okay, let's get a little perspective here. It's a common meme in the business that Microsoft makes more money selling software to Mac users than Apple makes selling Macs to Mac users. I'm not positive whether that's still true, but it would not surprise me in the least if it was. MS-Office for Mac still costs a king's ransom and still sells like hotcakes at Apple Stores everywhere.
Maybe I'm being naive here, but how could this possibly be true? Even if every single Mac owner bought a copy of Office for every single Mac they owned, wouldn't Microsoft still be making less money by virtue of the fact that Office is (hopefully? I haven't checked) cheaper than the Mac itself?
No amount of careful planning will ever replace dumb luck.
