Does notebook computer user need a mouse?

I have a notebook computer.And a mouse was addition to it.
It is very good design and match with notebook computer's design.

But I used it few times.Because I use a touch pad.

It was difficult to use it perfectly.But,I did it.
It's advantage is user isn't exhaust with it,it doesn't need wide space,and using it is cool( ^ ^ )

...Am I minority?
