iFixit got its hands on a shiny new 13-inch MacBook Air and tore the diminutive machine apart. On the outside, the new MacBook Air is similar to last year's model, but the innards revealed a few minor differences like a smaller SSD module, and updated AirPort card, a new heat sink clamp and more. They also noticed dual microphones that'll help cut down on background noise during a FaceTime call.
In the end, the MacBooks Air was awarded a Repairability Score of 4 out of 10, with 10 being the easiest to repair. The case is easy to remove and some the parts are easily replaceable, but several key components like the RAM, SSD and certain screws are proprietary. iFixit also confirmed that the RAM is still soldered to the Air's logic board, and the SSDs are not compatible between generations.
