My friend once told me an incident.

One day he was using Ubuntu and his 10 years old niece, who was only familiar with Windows, saw him using terminal.
She then said this, in an amused tone:

Oh my god Ubuntu is really smart. In Windows I have to point to things to make it understand. But here we can talk to the computer and it obeys?

I think she's right !! :)

Linux is like black hole. Once in, never out !!
