I have had my pebble for a few weeks now, and I actually like it a lot, even with it’s current limitations. There is a small uproar going on in the Pebble community because all the promised watch apps and the developer SDK has failed to appear yet. And I agree – I too would like to try writing cool apps for the watch. However, I do believe that will be available at a later point, and the watch is actually quite usable even as it is.
My favorite function is a very simple one. The motion sensor in the watch turns the backlight on at a flick of the wrist. This is so useful that all electronic watches should have it.
The main functions the watch has right now (apart from telling time) is SMS and mail notifications. SMS is flawless, mail works most of the time but not always. This is apparently a problem with the iOS API and the Pebble guys are working on it – or so they say. The watch also works fine as an iTunes controller.
A big drawback is unfortunately a severely diminished battery life on the iPhone due to the increased Bluetooth traffic. I used to get at least two days out of my iPhone before Pebble, and now I get barely one day. Irritating, but not really Pebble’s fault.
