Going to skip this one
I have one of the original pebbles and I think I'll skip this one. Their customer support was atrocious - to the point of being non-existent. That wouldn't have been such an issue except that they had some pretty enormous problems delivering on time, and then build quality issues, especially in the screen, when the watches finally did ship. They've replaced mine twice due to faults with the screen, and the new one has developed the same fault a third time.
It's a nice idea, and I do find myself using it, so like a smartphone, I'd miss it if I had to give it up now, but sad to say the next smartwatch I buy will not be a pebble.
