Aliasalpha: Hehe yeah I'm and IT guy so when someone asks me to network any form of computer (or a mac), step 1 is to open the command prompt. GUI's are for n00bs!
The Aqua GUI together with the command line is what makes me prefer Macs to other platforms. Everything in the GUI (ie. everyday usage) simply works in a fluid and logical manner, and the command line is there for when you need the full power of Unix.
I do admit though, that with Vista - and 7 more so - Windows has almost caught up, Gnome (and KDE I guess, though there has been some time since I used it heavily) isn't quite there yet though OpenSUSE's start panel/menu (using Gnome) helps a bit with launching apps instead of having to dig through a crapload of menus.
