I think that in general, most of the free software rocks.
Linux is just the kernel, the things that regular user sees are the things that make that "cool" feeling.
For example, KDE/gnome/xfce themed (with XGL?
) and other components of the UI make the woah feeling. When you have all the (free) software in it like firefox, gimp, openoffice... it starts to feel like usefull. And when you see it doesn't crash and runs smooth, you actually start using it, so it's all the free software that rocks!
I bet that most of you wouldn't even notice if all that ran on BSD or other *nix.
Linux
and (most) of the free software rocks.
Everyone in my home uses Linux and thinks Linux rocks, my sister can finaly install applications (Synaptic) and play all the cool games (Supertux), surf without worries using 5e PC. Im the only one still with Windows dual boot (DBP), I dont hate windows, plain and simple: it just isn't so advanced, flexible, cool...
