Yeah, Mac is a competent *NIX BSD system. The problem is the price and lack of control. Anyone who thinks Mac isn't on the Linux side 50% of the time hasn't used it.
Work only gives me the option between Mac and Windows, and I'll pick the *NIX 100% of the time.
In Mac Os you can actually pop open the plastic covers to reveal a pretty advanced control panel that feels oddly like Linux, but you have to do it very quietly, or else Steve Jobs will rise from the grave and slap you across the wrists with a metal ruler
