1. There are smart watches that are independent of phones and more will come.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?
2. Why can't you wear a watch at work? And if you can't wear a watch, why would a phone be accepted?
3. You have to charge all electronics. Why would a smartwatch be any different?
4. Smart watches can be water resistant. Some are, some aren't. Just like phones.
Now, beyond that, have you ever met someone with hearing problems or completely deaf? I'm one of those people (indoor and close quarter gunfire and constantly around helo/jet engines will do that!), so a smartwatch with vibration and instant on screens are invaluable to me. (I can't hear my phone in my pocket and most of the time I don't feel it vibrate either, unless I sitting down and the phone is pressed against my leg.)
This is a small niche case, granted, but it is just one instance where smart watches can be of great help.
