Hi, first time poster at the forum! I just received my new macbook air and just love it! I trying to decided between external hd and time capsule/nas for my media files and back ups. Would love the nas/time capsule option because i wouldn't need to carry and extra item with me all the time. Any suggestions? But my main question is that can a time capsule act as a server? Can i access my files remotely via internet? Yes, i know there was that back to my mac but i understand it needs mobile me. Thanks to everyone who offers help!
