This is a bit of a hand wave, sorry, but if you're okay with a 3 day battery life and want those features, then maybe the pebble is just not the watch you're looking for? I hear good things about the Garmin watches.

I deeply appreciate the battery life personally. Every time I charge it is an opportunity to forget to put it back on. I can go on a long trip and not worry about packing a charger. I can wear it at night to track sleeping more easily. And probably most importantly, with weeks of life, there's basically zero chance of me being surprised at 9am after leaving the house that my watch is about to die in a couple hours.
