Tablets aren’t the most powerful computing gadgets. But they are the most convenient.
They’re bigger than the tiny screen of a smartphone, even the big ones sporting nearly 5-inch screens.
They have longer battery life and always-on capabilities better than any PC — and will continue to be better at that than any ultrathin/book/Air laptop. That makes them very handy for carrying around and using frequently, casually, and intermittently even where there isn’t a flat surface or a chair on which to use a laptop.
And tablets are very good for information consumption, an activity that many of us do a lot of. Content creation apps are appearing on tablets. They’ll get a lot better as developers get used to building for touch-first interfaces, taking advantage of voice input, and adding motion gestures.
They’re even better for sharing and working in groups. There’s no barrier of a vertical screen, no distracting keyboard clatter, and it just feels natural to pass over a tablet, like a piece of paper, compared to spinning around a laptop.
