The activity tracking is the Pebble's killer feature for me. While I like getting notifications on my wrist, and being able to see the time whenever I choose is nice, what I really love is passive tracking of how far I've walked in a given day and how long I slept for. They've also just today released a mood tracking app alongside the rest of the tracking which prompts you once an hour for a quick summary of your mood and what you did in the last hour.

Being able to later go back and correlate all these things is awesome - even now I know that on days I get out and exercise more I'm happier, soon I should be able to give objective numbers on that, along with being able to determine things like the correlation between caffeine and happiness/energy levels over the day.

I'm pretty excited for the Pebble Core as well, especially since they announced Alexa integration, I think its got a lot of potential for drastically changing how we interact with mobile computing and moving on from the current interactive glass paradigm.
