Should I Get a Smart Watch?

I’ll admit:  I’ve always secretly wanted to be Dick Tracy.  Isn’t that really what smart watches let you do these days–talk to your wrist, send messages to others, fight crime?

Ok, maybe not.

What I really want is to not have to take my phone w/ me on a run!

Do you have a smart watch?  What do you like about it?  Even more importantly:  what do you DISLIKE about it?
