oh, and after getting used to running linux as a simple user, I recommend you start learning to do the real magic.
what really makes linux so powerful is shell scripting (though many people prefer python nowadays for it's prettier syntax and the power a full blown programming language offers).
i'll just give you an example of what you can do with it:
(this shell script is a gnome specific script, just to impress you with some GUI =P)
just follow the instructions at the beginning of the script.
copy and paste it into a file at /home/YourUserName/.gnome2/nautilus-scripts
to make it executable you need to type chmod +x ScripName
or right click it, choose properties and under permissions check the allow execute as a program...
if you want to learn bash scripting, you can look here:
