I had a Kickstarter Edition pebble. It was terrible, both in hardware and software. After a few months it developed an issue when the contents of the display disappeared, and I had to physically press the display to see something (googling this it seemed I wasn't the only one with this problem). It also supported running only 1 watch app at a time, which meant if I had a timer running and I got an SMS which took focus, the timer stopped. I would have thought that running a timer on a watch would be basic functionality...
