The Lenovo ThinkBook Flip concept has another fun trick up it’s sleeve besides its foldable display. Its trackpad has hidden LED icons built into it, allowing you to summon three layers of controls and handy shortcuts.
My favorite was using it as a number pad and calling up the calculator app on the laptop’s giant 18.1-inch screen, but it has other (more useful) features too — including custom user-defined ones.
