Apple MacBook Air (13-inch, 2015)
Good old MacBook Air, now with an unbeatable battery life
While other laptops continue to catch up to the Air, and even move past it in terms of design, the Air stubbornly holds onto its claim as having the longest-lasting mainstream laptop battery.
Along with a new CPU, you get the associated improved integrated graphics that are included with the Broadwell platform, as well as a speed bump from Thunderbolt to Thunderbolt 2 in the data/video port. The built-in flash storage, which switched to the faster PCIe interface last cycle, now also gets faster throughput, although in everyday use, you are unlikely to notice any of these incremental improvements.
While still a great all-around useful laptop, the 13-inch MacBook Air is stuck with a lower-res display and a design that is no longer cutting-edge. However, the blazing speed and super-long battery life puts the 2015 13-inch MacBook Air in a class of its own.
