i find it really curious. the phone is already a device for consuming notifications. now everyone is trying to sell a smartwatch to consume phone notifications.. its so meta...
In the sordid tradition of technology prognosticators, I'm going to make a prediction: there will never be a strong game market for the smartwatch like there was for the smartphone. Games work on the phone because the phone is what you stare at when you're bored. The smartwatch isn't for when you're bored, but rather for when you're busy, so there's no point in gaming on it.
