I think Apple really learned from Sony that they need to master the whole stack for a product. Windows was really a bad bad fit for Sony, i seriously think they should have bet the farm and tried to have their own OS, be it linux or a BSD variant and licensing a professional looking office suite. They did it with Playstation, they would have been in a better shape if they went this way from the start. About the cracks in Apple's integration, I think even the most vocal people only have mild complaints for now. But it seems money and power and mindshare are not enough for Apple to get the resources to fix these, and there are obviously planning to spread even thinner. I also think the competition doesn't have to be absolutely better than Apple, just bring unmatched features that would tip the balance for specific consumers. Like the digitizer in the MS surface, or waterproof android phones, etc. Once one of the device is a non Apple one, it brings the potential value of the whole ecosystem way down.
