I like those too and just bought a second one (2015 model) for the girlfriend. It seems a shame that they stopped making them. I guess maybe it was too much competition for the more expensive, usb2-less Macbook.

Clinging to my 11" MBA (2014) as well. 4-core, perfect size, indestructible. Totally agree that if they would make any modest improvements just to keep it current (proc, mem, wifi, etc.) I would refresh every year or two. I don't want the newer MacBooks with half the processor, no magsafe, and bad keyboard.
