1. Apple MacBook Air
Apple has a history of being first out of the gate. On June 10, the company unveiled the latest MacBook Air series built with Haswell, just one week after Intel began shipping its revolutionary new part. And the results are in. The power efficiencies of Haswell, when combined with Apple's already legendary power-saving algorithms, have allowed the MacBook Air to run for as many as 14 hours on a single charge. Ever modest, Apple rates the 13-inch unit at 12 hours. Either way, it's the most expansive stretch of battery life on the planet. But, there's much more coolness to MacBook Air than that. Apple includes Intel's latest HD Graphics 5000, supports the emerging 802.11ac high-speed Wi-Fi specification, and delivers two USB 3.0 ports and a 10 GBps Thunderbolt port, and of course its unibody design is as thin and light as ever. It weighs less than 3 pounds and is 0.11 inches thin at its tapered end.
