Notebooks in this category have displays that are 13 inches and smaller. They are designed to be light and easy to carry around. In order to achieve these light weights, some of these notebooks sacrifice features such as built in DVD drives and small keyboards, but they are great to carry around with you all day long.
There are two styles of tables that fall into this category, slates and convertibles. Slates are basically just a screen with all of the electronic components built into the screen. Convertibles look like a laptop complete with a physical keyboard, but the screen can swivel 180º and fold flat covering the keyboard and keeping the screen exposed.
