It is LCD writing tablet by sensing pressure. I think it is a cool stuff that a hardware can replacing the memo pad. It will save trees if people really use it seriously.
It is light (only 4.2 ounces), thin and no need to charge (but don't know the products life time). According to the feature introduction, you can create different textures and patterns on the LCD by using any suitable instruments --- even fingers.
I really want to buy it but it is out of stock in Amazon, unluckily so I can tell you the price right now.
