Apple’s lightest MacBook Air comes in 11-inch and 13-inch. It has been a part of the Apple lineup since 2008. But in 2013, Apple didn’t put sufficient attention on its MacBooks and minor changes have been seen from Apple.
Let's talk about MacBook Air 2014! One thing sure about this device is that it’ll pack Retina Display which could be of 2304×1440 pixel resolution. Apple is also very keen producing less power consumption devices. So, it could be a lasting one which is a great thing.
It’s likely that Apple will release the latest version of MacBook Air in the fall of 2014.
The existing 2013 model offers a battery that can last up 15hrs, thanks to Haswell processor. Also, the MacBook Air 11-inch and 13-inch include ultra-fast PCI-E which is the quickest storage leaving the PCs in the trash can.
Apple may shock us by releasing it with a 12-inch model as 13-inch model may be a heavy one for someone and 11-inch isn’t wide enough to give the large display experience. So, 12-inch is a possible option for Apple to put it on MacBook Air 2014.
