Lenta.Ru, citing CrunchGear, reported that the company Improv Electronics has released a liquid-crystal tablet Boogie Board, designed to replace paper notebooks. The device uses Kent's Reflex LCD surface Displays. Reflex LCD is a plastic that reacts to pressing and keeps writing.

The device does not need energy when drawing. It is consumed only when erasing. (By pressing the logo on the top panel.) A small battery is built into the LCD tablet, with a charge of 50,000 erasures.

For drawing attached stylus, but you can use any solid object. The new device is sensitive to the force of pressing, which allows you to draw lines of different thickness on it.
As far as can be judged, only one color is available to users - yellow. In addition, you can not erase part of the written. Also, the Boogie Board cannot yet transfer records to another device - a computer, laptop or mobile phone.
Boogie Board costs about 30 dollars. (At the moment, there is an announcement on the main page of the site that a gadget is shipped only in the US) It is alleged that the cost of each erasure from the Boogie Board is 15 times lower than the cost of a sheet of a regular notebook.

I'd add from myself that the promotion of its environmental friendliness is very noticeable in the promotion of the Boogie Board.
