A simple Notebook has a mess of advantages over a tablet: It never needs to be charged, it`s cheap, it`s lightweight, it produces a tactile feeling that styluses haven`t yet managed to reproduce. It might even encourage creative thinking, make you more focused, and keep you sharp as you get older. And it`s always booted up to the right app for taking notes. To pull out a thoughtfully chosen notebook and a nice pen conveys that the owner is classy and undistracted by whim.
