Recently the webpage IFixIt bought a MacBook Air with the only purpose to show what Apple worked very hard to hide: the inside of this machine. Many of you sure have hear about the 5 battery life on this machine but what I have not noticed is somebody saying that we are talking about a battery that cannot be replaced by the user. 5 hours is not that much for many which netbooks are the only one and main PC. So keep that in mind. It seems that Apple’s engineers try hard to get the maximum battery life following the same design applied in the iPad. The battery of the Air virtually occupies more than 70% of the bottom area of this machine. Beside the iPad battery I never has seen something that big in proportion with the machine.
