I just posted a comparison review of the Pebble vs Fossil Hybrid Smartwatch. [1] I'm still on the fence about whether to keep the Fossil. The main con is that it doesn't allow notifications from any app (just a dozen or so they've hand-picked, for now), and that the light does not come on easily. But the battery life is comparatively amazing (2 weeks).
The most interesting thing I've noticed is that because it doesn't look like a smartwatch, when I look at my wrist to check a notification, people ask if I'm OK on time. They assume it's a regular watch, and therefore the only thing I could be checking is what time it is. Kind of a funny side-effect of having a well-camouflaged hybrid smartwatch.
