Well, a far so good. Quick thoughts...
I like it quite a bit! It's quite different hardware wise from the MetaWatch that I've been using; a lot thinner, but a touch longer.
I already bought a screen protector...there's no way that this will stay scratch free for very long without one.
All notifications work really well. There are people saying that they were able to get Handsent to work with Pebble, but I haven't had any luck yet.
The music player controls work nicely too. There's quite an impressive list of compatible music players to chose from. However, there is no volume control as of yet.
