Ask HN: Do you ever use the numpad on a keyboard?

I am using a tenkeyless keyboard (a keyboard without a numpad) at work and at home. When I decided on the keyboards, I felt that I never use the numpad at all, therefore I decided on a 80% keyboard. A few days ago I bought another keyboard for my son and realized that keyboards without numpad are still the exception. Also, all non-Apple notebooks seem to have a numpad, which has the annoying side effect that the touchpad is not centered on the notebook's body. I was willing to pay extra money to get rid of the numpad when I recently purchased my notebook, but the option was just not available.

In my opinion numpads are just a leftover from computers being mainly used for data input and are just not needed for most uses today. Additionally they occupy valuable space on my desk.

My question now is this: Am I missing something? Am I doing something wrong? Do you ever use the numpad?
