Seriously?! Why would I want a watch over a phone? Don't think the functionality they'll be able to put into an iWatch will make the iPhone irrelevant. Just look at the Galaxy Gear it is handicapped without being connected to a companion device. Come on buddy don't you have something better to do?
At first I was against the idea of a watch but have now since changed my mind. I hope Apple will create an elegant one to squash the competition. Secondly, I would not forsake the iPhone for a watch. That just doesn't make sense.
If Apple ever comes out with an iWatch, I'm sure it will complement the iPhone and the iPad. I'm pretty sure that Apple would never do anything that would hurt the other Apple products...
