this is just what ive been looking for.
its an adaptor for a micro sd card that sits flush with the edge of your macbook air or macbook pro case.
it means that you can add in an extra 64GB of storage space.
hopefully by the time it gets launched we can get 128gb micro sd cards – that would let me have all my music collection and all of my photos on the mac (right now they are on my NAS, which is fine when im at home, but not much use when im on the road and have no net connection)
