Carrying a phone around with me allowed me to stop wearing a watch. I'll wear a watch again when the phone is in it, not in my pocket.
Like wise, I've not worn a watch since work gave me a pager back in 2000 or so. How long until the watch is the phone? I've no idea where the mic and speaker would go, I for one would not want to wear and ear piece all the time, and holding the watch up to my ear would be tiresome. May the iCochlear?
All this talk of digital watches reminds me of Douglas Adams:
Far out in the uncharted backwaters of the unfashionable end of the Western Spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this at a distance of roughly ninety-eight million miles is an utterly insignificant little blue-green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea...
