Designed with designers in mind, this MacBook Pro 2018 concept explores the integration of a full-size touchpad in place of the traditional keyboard. It relies on Apple’s own Taptic Engine system to give the user the feel of physical buttons or even emulate a scroll wheel or sliders. It retains the touch bar for shortcuts and function keys but the entire surface is touch enabled! More at YD.
I guess this makes sense given that the current MacBook keyboard is already verging on being completely flat.
