I'm super happy about the revival (I backed the first Pebble Kickstarter) and the bullet list of key features you're targeting would make my dream watch, but I hope you take this as constructive criticism that you're way off right now on this one:
- Simple and beautiful design
It's ugly, and the gap with the industrial design of today's watches is wider. I suggest contracting with a good industrial design firm to redesign the case: the case material, screen and internal electronics can remain the same.
