You can buy the touchpad seperately. Which makes sense, because you don’t know where it’s ergonomically correct to put it for individual users.

I place mine rather far to the left. Most right handed people won’t like that setup.

Twelve South and other firms used to make gizmos to pair the then no-numpad version and trackpad so they'd work on your lap or as a Mac Mini living room media center accessory etc.

Was fantastic. Apple should MagSafe that jazz.

I also wonder about this.
