A Windows laptop computer that can be switched to a tablet style. Also called a "2-in-1," the screen folds back all the way around, turning the machine into a rectangular slate. Because the keyboard is still attached, convertibles are heavier and thicker than regular tablets without keyboards. Convertible Vs. Hybrid The convertible's screen remains on the unit, whereas the screen on a hybrid laptop (a "detachable") is removed to become the tablet. However, the terms "convertible" and "hybrid" are used interchangeably for both kinds of these double-duty machines. See hybrid laptop, tablet PC and Windows 8.
