I'm surprised nobody has mentioned the loss of the ESC key. I use Vim and touch that key all day long. Replacing that with a touch button sounds like a terrible idea for usability. Clearly nobody in charge at Apple is also a vi user.
Beyond not removing the ESC key, I want 32-64 GB RAM, a 2TB drive option (or more), and no more weight.
Typing with my splinted-for-carpal-tunnel hands: for the love of God, if you're using vim all day, then map Esc to CapsLock or something else near your home row, or one day you will be wearing these things too.
