Travelers place a lot of value on the weight of a laptop, and at just 2.4 lbs., the VAIO Pro 13 is the lightest 13-inch touch-screen notebook yet. That's thanks to its carbon-fiber chassis, which houses an Intel Haswell Core i7 processor, a 512GB SSD with a PCIe interface and 8GB of RAM. Sony also found a way to cram a battery that lasts more than 7 hours on a charge into this 0.68-inch-thick chassis. Add the optional slice battery, and endurance jumps to 14 hours. That's long enough for Santa to travel from one end of the country and back.
