I think there's an inversely proportional relationship between the 'magic' and the perceived 'power' that conventional linux users crave.

The 'magic' that Apple has repeatedly demonstrated has to do with making computing simpler and reimplementing real world objects\workflows\analogs into their interface design (to make things more intuitive) - both of which are generally shunned by power users.

At the end of the day Apple designs their products for the regular Joes and Janes, and capitalizing greatly from it... and much of the FOSS userbase simply don't appreciate the same thing as them (although they seem to secretly envy parts of Apple's positions/assets).
