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. HybridThe 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.
