Best thing, is the new display on the MBP's.
Worst thing, leaving the iPad1 out of the iOS6 updates. oh and no updates to the iMac or Mac Pro range.
Stupidest thing, combined USB3 and USB 2 ports "That's not how we do it." USB 3 and USB 2 will be the same port. Which has been done for some time by others, just with blue plastic to let you know it's USB 3 capable. Big whoop Apple. In fact that's going against the "Look at me, I have something you don't" Apple mentality
Getting Siri to start Apps is no biggie, other voice recognition apps have been doing that for yonks.
Mostly incremental updates, biggest surprised was the Retina Display.
