Toshiba is entering the Chromebook fray with the first 13-inch notebook running Googles cloud-based operating system. Toshibas Chromebook weighs just 3.3 pounds and is 0.8 inches at its thickest point. Its design makes it look like a mashup of Toshibas Kirabook and Apples 13-inch MacBook Air, which is not bad company to be in.
