I agree with your analysis of the watch as a notification device. But with regards to the smartphone - the major killer apps it had we're: solving boredom(browser+games), better communication tools(facebook), and gaining access to lots of info everywhere(browser). Some of this things are based on strong psychological needs and many of them are addictive, so you got killer apps. In theory, glancable notification might have been addictive, but after trying it it appears that it isn't for most people. But it's not to say we won't have killer apps for the watch. The thing that i find most damning for the watch is that we lack even visions of killer apps for the watch, while we certainly did have visions about the phone before it appeared - people did want to browse on the go. The only interesting and realistic vision of the watch i've read is that it would be an identity device(easier payments, opening doors, etc) and a UI for our home automation devices plus a notification device. It's not a very interesting vision, it's just buys people a little bit of extra comfort and isn't really useful unless in very specific context(like running). But who knows, maybe that combined with the fashion, being a status symbol and apple's involvement will sell well.
