When plugged into its included keyboard dock, the ASUS Transformer Book T100 changes from a light, 1.2-pound tablet into a laptop that will last up to 11 hours. You’ll also get plenty of productivity out of this quad-core Bay Trail device, be it a day of classes or a cross-country flight. The 10.1-inch IPS display (1366 x 768 pixels) offers a bright picture and wide viewing angles, which are great for watching movies and playing games. And when it's time to get to work, you'll appreciate the bundled copy of Office Home & Student 2013. At $349, tablet hybrids don't get much better--or cheaper--than this.
