Another way to look at it: what makes Apple successful is at odds with how the components of the Linux desktop come together/are built. In order to provide for a consistent, interoperable experience across the stack, you need control of its components. Apple's vertical integration (now making chips!) gives it the ability to make changes in order to provide the 'best' experience (best as in, profit; taking into account consumers express their opinion with their $). The Linux desktop optimizes for freedom: you can choose what parts you want. That's not conducive to a consistent experience. One could argue that's not the point. If you want 'the desktop' just buy a Mac. If you want 'the Linux desktop', it's been there for a while now, just go ahead and glue together the parts - that's the point!
