I think I'm going to return mine as well, which I kind of hate to admit to myself. I really like it, but I wanted to love it.
I like the rotating bezel a lot, I LOVE the screen, it looks amazing and the resolution is great. Plus the overall interface is really cool, very fluid and smooth. But as somebody said earlier, it's mostly just different, not really better. The interface certainly looks better compared to the anti-interface of AW. The problem is that the core functions that I use my smartwatches for are way too cumbersome to use. Voice recognition is pretty terrible compared to Google, when it does recognize it correctly, I usually get a "refer to phone" or "let me look that up on the web" message which does nothing. Texting via voice still requires several touches of the watch face, unless I'm doing something wrong, which to me completely defeats the point. With AW I can say "Text Bob I'm running late", and done. Nothing else to say or touch.
Notifications are pretty good, I like the way they are laid out and how they look, but I miss them a lot, don't know if it's just not vibrating or what. And from the home/watch screen, you can't really tell if you have missed notifications or not, depending on your watch face of course. Don't even get me started on how terrible the maps function is!
So at the end of the day, I do like it, but I'm not going to sit down and read CNN on my 1.2" watch screen, and I can't easily text... But damn the battery life is good!
