Warranties be damned, iFixit got its hands on the newly announced MacBook Air and immediately did its thing, digging into the super-thin laptop like a kid at Christmas. Not all that much to see from the outside of the device, save for that new Thunderbolt port and some shiny new keyboard backlighting. Things are a bit different inside, however, including an Intel Core i5 processor, a Bluetooth 4.0 chip, and a general lack of thermal paste. As for putting the thing back together again -- the Air scores a four out of ten for repairability, so maybe don't try this at home.
