Anyone doing accounts and data entry wants a numpad. My dad recently damaged his laptop keyboard. I gave him a spare usb keyboard, and he still went out and bought a new keyboard just for the numpad. There's a reason pc makers keep stuffing those lopsided monstrosities in there
Anyone doing data entry with a numpad will also want a proper one, not a squishy laptop one.
But they're clearly not the majority of the people - the rest of us have to live with a lopsided keyboard because a few people for some reason do data entry on a laptop keyboard.
