I hate to sound like an Apple fan but you're an Apple cynic, maybe we should both consider our views more objectively. You should consider that the dramatic improvement you think is coming in the next year, maybe actually is coming in the next year; as in right now in the Apple watch. I have a friend with the Pebble and another with the Galaxy Gear. They are both good smart watches. But there have been more than one conversation like this: "Hey let me show you this. Oh it's not working, hold on a sec. Uh, maybe I have to do this? No, wait. Yes here it is. Actually no. Well anyway I can set it to do this and it's really cool".
There won't be a huge leap in battery tech this year. Battery improvements are a slow march. In terms of obsolescence, next year there will certainly be some marginal spec bumps and a cool new feature, it's what they do. But the iwatch is arguably entering the market as a mature technology. Smart watches have been around for quite some time, Apple is just the first to make a billion dollar engineering design / software / support bet on them.
