The 2014 MacBook Air refresh was a mere speed bump, but the range also went down in price. The lower-specced model in each screen size is down £100, with the high-end versions £130 cheaper.
The MacBook Air is otherwise unchanged. The range uses Haswell processors, which are designed to use very little power. The graphics chipset is significantly speedier than its predecessor, and the flash storage is up to 45% faster than the 2012 model, or nine times quicker than a traditional hard drive. 802.11ac Wi-Fi made its Mac debut with the 2013 Airs, and it’s up to three times quicker than 802.11n. Battery life is awesome, with the 13-inch models lasting up to 12 hours, and the 11-inch MacBook Airs running for up to nine hours on a single charge.
