I'd be happy if it just used some low-power communication to relay information from my phone. It doesn't need a big touchscreen either. Imagine a "smartwatch communication standard" that let normal good-looking watches with months or years (or perpetual) battery time display info from all smartphone platforms would be fantastic. That way I could get an expensive watch and not have to worry about whether it's going to be an expensive paperweight in a few years. I'm happy to buy a $1000 smartphone, but a $1000 watch I want to use for a decade, even if its smart features don't work any more.
