So what makes for an impressive tablet? We look for ones that have crisp screens with 1080p (or better) resolution, bright color palettes, interfaces that are pleasing to look at and easy to use, speedy and power-efficient quad-core CPUs, and designs that are thin and light—without feeling flimsy and cheap. The best of these tablets come at a premium, around $500. For that price, you want a device that offers extras—multi-tasking and kid-friendly modes and a wide array of content options—on top of all the basic criteria. Free stuff doesn’t hurt, either.
