Today's 8-inch Windows 8 tablets provide a great mix of portability and productivity, and Lenovo's Miix 2 is the best value in its class. Powered by a zippy Bay Trail processor, the Miix 2 offers a bright 1280 x 800p display in a sleek frame. You also get 8.5 hours of juice with this slate, so you can use it all day on a charge. Best of all? The Miix 2 costs a pocket-friendly $299.
