Smartwatches will fail. It <i>seems</i> a cool idea, but like Dick Tracy's wrist-phone, wrist-calculators, and wrist-watch computers (they've been around for many years), they won't take off. Most of us stopped wearing watches the moment we got cell phones. Smartwatches are awkward, and an even smaller display than a smartphone - which are currently increasing in size.<p>Better is a bare headsup device - a "display" as big as you like, without being bigger. Google Glass <i>sans</i> camera (so no privacy concerns til we're ready for it).
It can even have the time in the corner...<p><i>EDIT</i> yes opps, s/phone/watch/. Ironically cut/paste was failing on my smartphone, as was I.
