maybe. i don't see the appeal of 30 days battery at the expense of such relevant features. 3 days would be more than enough for me. also, considering that the watch is practically useless without a connected phone, advertising its excessive battery life is questionable.
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.
If he had built the feature set you're suggesting, and with the battery life it would require, he'd be competing directly with Apple, Google, and Samsung. And he'd have no key differentiator.
The reason Pebble has a chance at success is because they carved out a niche years ago, and for some reason no one decided to occupy it in their absence.

It can still tell you the time. Its primary function is a watch.
It will drift, significantly, without being connected to a device to set the time.
...by, at most, a minute or so each year.
At least, that's what quartz watches could manage in the early 90s, as does the clock in my microwave oven from the early 2000s. Why would a modern disconnected device would be any worse?
I'd suspect that a watch like the Pebble isn't syncing time with a Quartz crystal but by counting processor ticks - that would be a lot less precise in the long run.
