The chromebook also has the same charger as most of the android phones. You get 100gb of free drive space. There is also a app store. I come with the basic google apps already like the google drive, maps, play, docs and gmail. This also would be the clearest picture you would ever watch. The chromebook would be great for video chatting and watching videos via internet. The chromebook has curved edges so that your wrist don't hurt from typing a fitted keyboard for big or small hands. It has two USB ports and the speakers are around the keyboard so when you play music or something like that it comes straight to your ears rather than your lap.
