Being someone who likes the command line, one of the best features of OS X is that it is based on a UNIX variant. This means that it has a ton of power that is hidden behind a stylish GUI. If a user does not want to use this power the operating system functions just fine without any tweaking. The fun comes in when you want to change something and it can easily be altered. You do not have to go into the registry like in Windows, but you get to enjoy the goodness of UNIX’s power.
I just came across a post on O’Reilly’s MacDevCenter that was just updated dealing with the difference between OS X and UNIX. This is a great reference and I really wish that I had found it earlier.
