The demo today was pretty cool. I'd be interested in a Sport edition. Probably wait until second gen though. Maybe even the 3rd gen and get the 2nd for $100 less. I want to meet the person that buys the Gold one with gold band for 10k. That is absurd.
The new 12" Macbook is beautiful. Although I'm disappointed in single USB 3c port. I can live without a disc drive but i usually have a second display and the power attached to my Macbook Air. I'm assuming there will have to be some type of dongle to support both simultaneously.
