The Verge:

There are a couple of significant downsides that temper my enthusiasm for the new Gear. First and foremost is the speed and intuitiveness of the user interface — or rather, the lack thereof. There's a tangible lag to anything you do with the Gear, while the swipe gestures are hard to figure out and do different things depending on where you are in the menus.

Add to that a bad speaker, short battery life and a price at $299, what’s incredibly great?

I get that it’s the first release and that it is going to get better over time, but it certainly looks like something rushed out in case Apple comes out with a watch too.
