I must admit I bought this on a whim as a birthday present to myself because I fell in love with the cute hummingbird design. The case seems functional and does just fit a 13" MacBook Air with a Speck hardcase on it. There is one outside zippered pocket that runs the length of the case. It easily holds a superdrive and the basic power supply. I am not sure that there would be room for the additional optional cord that goes from the power supply to an outlet. It would be a tight fit at best. The shoulder strap is comfortable. I have not yet taken it on the road for any substantial travel so I can't comment on the sturdiness. If your aim is purely for a functional case the InCase sleeve which I could only find in black and had already bought when I saw this one may be a better choice. It has more storage room because there are pockets on both sides, though one has only a velcro closure in the middle.
