mac users pay for it (Score 4, Insightful)

There's another reason for continuing to produce Mac versions of Office, which is that this market usually pays full retail. In the Windows/Linux world, it either comes preinstalled, or you steal it, which is to say, borrow it from your pals or at work. Since it is so ubiquitous, it's easy to find copies. When Linux was my sole desktop, I always had "borrowed" copies of office running on crossover office, for when openoffice.org compatibility wasn't good enough, or when I had to look at some access database. I don't have it on my Mac laptop, because I would have to pay handsomely for it.
