We have an old unix beast at my office that still runs some crap coded in the early eighties. I think it predates Moses. I'm telling you, it doesn't get any simpler.
I also find I run my most of my mac using spotlight. It just seems like it takes less freaking effort to "spell out" what you want it to do rather than navigate a mouse arrow.
That pretty much sums it up for me as well. OSX being unix just makes me hate windows that much more, especially when I'm forced to use windows on the command line at work.
