I'm not him but I've had one of the first Pebbles - and love it. I was in the first thousand of kickstarters shipped so I've been using it for a while. Pebble + some of the software (especially looking at their card UI in 2.0 beta) is awesome.
BUT
With the Motox, the only thing the pebble does better than the phone itself is function as a trusted device and give you watch access to change the ringer (slick pebble app) and see who's calling if the phone's not nearby. Those are nice features, but I also am a bit of a watch snob so I love wearing my mechanical watch. When I do that, I use the Moto skip that I put on the watch band, so I just tap the middle back of the phone to my watch to unlock it when I'm not wearing the pebble.
