New GNOME user

My brother Jorge had recently his laptop, running WinXP, not booting
anymore. It just froze on the WinXP startup screen. I had a look, booted
from a Debian CD, and everything seemed ok, so he brought the laptop
back to the shop, where he was told that the computer had 70 virii!!!
I don’t know if that’s really true, but the fact that he had unwanted
stuff installed, and that the guy in the shop fixed it, is true.

So, as he’s seen, and used, several times my Linux laptop, he decided
he wants to put that on his laptop. He’ll be coming home one of these
days for me to install it for him, and, of course, he’ll be running
