Apple comes from the tradition where hardware is just a platform for software.
That's totally why Apple allows you to install OSX on any platform, and why no one cares about the shiny brushed aluminum cases or paying extra for getting a black MacBook instead of a white one -- because dammit, no one cares about the hardware! Seriously, though, my bad attempt at snark aside, isn't the Apple philosophy high-quality hardware that you never have to muck around with? Isn't that their justification for the somewhat higher prices?
An authority is a person who can tell you more about something than you really care to know.
