I truly am curious as to the reasons. The reasons I will never use one (should be careful throwing that N-word out there): Can't work independent of the phone that I ALREADY carry around and can look at quickly enough. Can't wear it at work, so why bother? Have to charge it. Pretty expensive just to save me a few seconds to pull my phone out of my pocket. Regardless of who designs it, my wrists are toooo small for most normal watches and smart watches, EVEN Apple's (which is a very nice design imo) are too bulky. I am guessing they are not water resistant? So more restrictions on the device. So why do you use one or want one?
