^^^^^^^^^^You make your mom run Linux? That's nasty.^^^^^^^^^^^
I fail to see why. It's easier to run than windows.
I like how you deflected to this instead of arguing the ease of seeing the IP address every time a reboot is done.
I can guarantee moms everywhere would find it easier to just look for those numbers upon reboot than to worry about what a control panel is and which control panel needs to be accessed, or even what's a command line and what's an ipconfig.
The problem with your logic about it being easier on reboot is that most people aren't aware that they need to know their IP address until after their computer is booted up.
As for the difference between ipconfig and a control panel, that's like the difference between using vi and Microsoft Word to write a letter. Or Pine and Outlook to manage email. The graphical interface is easier to intuit, whereas the console method requires specific knowledge of the commands. For most computer users - intuiting is much preferred over referring to a manual for a console command.
