The software looks nice, but it doesn't seem to solve the broader problem with smart watches for me -- the lack of use cases. I can't think of a situation where using a smaller, less-responsive screen would be better than just pulling out my phone. I don't need stock information at a glance. Voice recognition isn't good enough to do any meaningful text communication on the things. The navigation stuff looks usable, but I wouldn't use it while driving. Google Now isn't good enough at answering questions or doing tasks that I can trust it not to screw up -- and those screw ups would have to be fixed on my phone, anyway.

I know some people who have used these things, and they've said that the notifications are kind of nice -- but even that sort of sounds like a nightmare, to me. Constantly having something tap my wrist for attention, or vibrate, or ding? How would I ever focus on anything? Do I really need to know any of this stuff right this second?

The entire category of devices seems like a solution in search of a problem to me. They can update the software all they want, but until it does something better than the experience of just pulling out my phone, it's just not super interesting to me. And, judging by the sales of all these devices, it's not super interesting to a lot of people.
