There are rumors in circulation of Apple planning to release a new 12-inch MacBook Air this year, which should features a slimmer design that current models, and it appears that we have receive confirmation to those rumors with a leak. Chinese site iFanr, has uploaded photos which apparently shows off 12-inch display assembly for the rumored 12-inch MacBook Air.
The new 12-inch MacBook Air is expected to be launched before the end of Q1 this year, so if the rumors are true we should get an official confirmation by March. So we could see the official launch alongside some new iPads in March.
In addition to the rumored thinner frame, the 12-inch MacBook Air is said to come with a single USB port which will be used to charge the notebook as well as connect devices. Even though the leak of the 12-inch assembly proves that the MacBook Air could be imminent, you should take it with a grain of salt until we hear more during 2015 Mobile World Congress.
