I ran out of hard drive space on my 2010 MacBook Air, and so I decided to upgrade the SSD. The OtherWorld Computing SSD kit and instructions are very straightforward. Opening th MBA reveals shockingly clean lines that are frankly beautiful and fits with the Jobsian aesthetic of being beautiful in the totality of the device. I felt like I was looking at an alien artifact. The fan which you didn’t realize was there has silent gears and fits in organically. It was like operating, changing out the SSD.
