This is one of those questions that I've always had and never really figured it out. Why don't they just stop licensing Windows and Office to Apple? Businesses and many people cannot leave the Windows/Office environment, but they're able to compromise b/c Macs can run both platforms. If MS starts being evil (well, more evil than they are now) and stops licensing Windows and Office to Apple, that would really hurt Mac sales IMO. I know that Mac sales is only a very small part of Apple's portfolio and the market, but on a broader scale it's also a war between platforms and ecosystems. The more people use iOS, the more sense it makes for them to adopt OS X. Not being able to access Windows/Office on the Mac platform could deter a part of the market from doing that.
