Re: Samsung's watchphone
I don't think they'll become popular.
1) Watchphones are weird to look at, and I don't think it's ergonomic, if you have to talk into to your watch that way.
2) Phones are more than phones nowadays, they're cameras, DAPs, MIDs etc. and watchphones can't keep all that in such small size.
They've never been popular although the idea is pretty old. You'll have to leave your watch to be charged and stuff so it'll be annoying at times.
