Another thought...
Will they make this 'new' Thunderbolt connector reversible?
It's taken USB how many years now to finally bring out a reversible connector? If this standard is going to stick around it might help if they don't overlook something that simple. It drives me insane that we've not bothered to improve on the Classic USB socket for so long, especially after a dozen stupid non reversible versions.
I have to admit I really like the Lightning connector, obviously Apple wouldn't let everyone use it royalty free but that would be awesome if they did. Small, robust and reversible - everything current USB is not.
The current Apple lightening cable is what 16pins but only 8 active as Apple only uses a one sided socket, so they only need 4 more pins for the current thunderbolt cable. MiniDisplayport connector is already 50% wider so 20+ pins in the same style of connector as lightening should be more than doable.
Would certainly make for a thin laptop.
