The Boogie Board tablet is the tree-friendly electronic alternative to paper, pencils, and pens.

It looks like a digital blackboard and actually functions like one. There’s no need to pick up a piece of chalk to write on it, though. Simply use the included stylus, your finger nails or any other instrument that will apply ample force. It will register all the scribbled images (responding appropriately to varying types of pressure) and keep them displayed until you hit the erase button.

Technically an LCD tablet, the Boogie Board uses Kent Displays’ proprietary Reflex LCD, a pressure-sensitive, battery-powered plastic screen that can receive and display on-screen input. The LCD panel itself can work without power, but requires use of an installed watch battery to reset the screen into a blank slate. The battery will last for up to 50,000 erases.

Keep one by the home phone and by your computer at work to jot down memos, make to do lists, leave messages for others, capture your next big idea, and more. Keep one in your car, and you’ll never be caught again looking for a piece of paper and pen to write important to-do’s to get from the grocery store on the way home.

The Boogie Board is $29.97. Learn more here.
