I'm skeptical about a few things - mostly regarding the dial. They are trying to replace pinch-to-zoom, but how does it know where to zoom? Also, the main UI screen with all of the apps looks ridiculous. They don't want you touching the watch, unless it's to click on a tiny app icon? I need to see this in person.
I wonder what the experience will be like for left-handed people. Can the watch be rotated to have the dial on the opposite side?
Overly not impressed by the crown control... people who wear watches that need to be wound rarely do it while it's on their wrist. I would need to feel this "dial" control to be convinced this is a good idea.
