I still have my 2009 MBA (2nd Gen) with OWC 64Gb SSD and a whopping 2Gb RAM. Its in showroom condition with one exception - the hinges are beginning to loosen a little. Unfortunately Apple has ceased the free hinge replacement program. It came with Snow Leopard but is currently running the Yosemite beta - the fans spin up a fair bit but the SSD keeps it quite speedy. So, what should I do with it?
