Haven't worn a watch on my wrist in 20 years. No plans to start either.
I think this is the problem that Apple will face with the iWatch: not a lot of people actually *wear* watches any more.
20 years ago it would have been unusual for anyone to not wear one, but now if you take a sample of random people on the street I'd be surprised if more than 5-10% were. It's something that is no longer necessary in day to day life.
Perhaps in order to be successful, the iWatch needs to not look like a watch.
