I, like others, don't use the numpad. In fact, at home where I use a bluetooth keyboard, I still use laptop layout, but that's just my preference. 

Anyway, you have two options. If you never travel with your laptop, then I would go get a keyboard that you like. Try several and see which one fits you best. If you do travel with your laptop, then get an external numpad. That will fit in a laptop bag and shouldn't take up much room.
