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?
You could put the bands on reversed, and the software could invert the screen but the knob would be on the bottom, vs. the top. It would work though not ideal.
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.
I need to see this in person.
