I bet your notebook is not as cool as the Rocketbook. This is a cloud-enhanced notebook that you can erase by putting it inside your microwave oven. You get to write using a pen and paper but your notes are uploaded to the cloud and organized. Each pge has 7 icons at the bottom, allowing you to assign each to the place of your choice.
The Rocketbook, when used with Pilot FriXion pens, can be erased inside a microwave oven. There is also an app that converts your notes and drawings into digital images. The app is available for iOS and Android devices. You can find it on Indiegogo.
