Jason Snell of Macworld has posted his first impressions of the newly redesigned Macbook & Macbook Pro which are quite comprehensive for impressions (link) .
Very cool that you can use iPhone headset with the notebook but am slightly annoyed that switch between using graphics cards in Pro model is not handled automatically when attached or not attached to the power adapter. You have to logout for the switch to take effect ( a little annoying Apple ) so hopefully some type of fix can be implemented by Cupertino in a future software/firmware update.
Still, won’t stop me from purchasing one in next 3 weeks.
