Why is the numberpad on the left side? Any ergonomical reason for it?

There are two main reasons. One is that is it for left handed people who can do data entry better with their left hand. The second is that some people like to keep their right hand on their mouse while doing data entry with their left hand. Typically, these problems are solved with external an  numpad, but keyboards like this are also an option.
