alt Hacker NewsPebble was my first smartwatch, all the way back in 2015. It was fun and quirky back when it was first released. Then it stopped production for many years while smartwatch category grew. Now they're coming back with same/similar models as before.
For me, its value lies more in nostalgia than anything else. I don't expect it to ever compete with the likes of my Apple watch for smart features, or a Garmin for activity tracking.
That said, it's an e-paper display so battery life is pretty good. Plus it had (and probably will have) an active community of small apps and watchfaces, which kept (and probably will keep) it from becoming stale quickly.
It's a very minor distinction, but they aren't a epaper display (low refresh rate, zero power to maintain an image), rather the technology is a sharp memory LCD (ludicrously low power, but high refresh rate). They're extremely neat and don't suffer from the washed out color and ghosting that epaper does, at the cost of needing ever so slightly above no power to keep an image displayed. I much, much prefer them even though Sharp doesn't really advertise them anymore.
