I was watching the WWDC last night because... yeah, that bored. But it turned out to be really interesting. I especially like the changes to OSX, all the tweaks to performance and battery life are impressive.
This was "cool". Useless but like most R & D shows all sorts of promising new directions. All running on an iPhone.
Action starts at 1:00.
As for iOS in the car, I don't like it. More **** to distract you while you're supposed to be driving. I liked cars when they were machines.
