Hello, I am considering buying a macbook air once the new ones come out. Wether I buy the new one or the current one I will decide later. My real question is (this will help me decide on wether i buy the 13" or 11": Is there a good way to get an external drive that would not stick out of the macbook air. I was thinking about putting an sd card in the 13" sd card slot, but I think i heard that the card does not go in all the way, Any good small foot print storage deviced for the usb port? (I was thinking of a really small adapter and micro sdhc card...) Thanks, Paul!
