The gross margin (36.2%) is obscene, yes (Dell has 18% I believe), but after wages, marketing, R&D and all that stuff, the actual net profit percentage is around 9% (6% for Dell). So Apple blows more of their earnings than the other companies do. OS X development and more R&D would account for some of it, but I also have a feeling that they spend ludicrous amounts on advertising. Those "Hi, I'm a Mac" ads better have excellent entertainment value, because you're paying a lot for them.
Not remotely correct.
To be clear: Dell's revenue of nearly $68 Billion for a corporation valued at $21 Billion should give you a clue that Dell's 81,000+ employs should be cut in half, but it can't since it's bulk comes from manufacturing/assembly. Dell would kill to get Apple's products to assemble, but of course it never will [both for personal and business reasons].
Dell signs and innovates their own Operating System driving standards changes throughout the industry.
Dell offers Windows and Linux [the better option but still not the best distribution] for it's product line.
Dell doesn't have a differentiator to drive their own market because Dell doesn't have their own market.
Apple with 35,000 [large portion in the retail space] is now achieving gross revenues of 40 million per 1,000 employees. Those are nice ratios. Dell on the other hand is not remotely close.
