Is it remotely possible this time? I am developer; a communication systems engineer. I am trying to let go a macbook pro for some of the features of a macbook air. Precisely the need for a fast, battery efficient, lightweight machine. I do have a macbook and an iMac. 3G seems to be a requirement for most of the tasks if I'm not covered with WiFi. Is it possible that the next set of MacBookAirs come with 3G inbuilt?
