Talking about 'productivity' from a watch? You mentioning the screen size is too small just makes me laugh. It's not like a computer where you can have unlimited screen size - the size of any watch is limited by the size of your wrist. What kind of productivity do you possibly expect from something that has such a tiny screen size? Apple Pay, checking text messages, answering/declining a phone call, checking emails, etc. are definitely MUCH more productive than any of the classical watches. That being said, please don't get me wrong - the Apple Watch is FAR from being perfect. Some apps still takes forever to load sometimes, battery should last longer, and things just don't work flawlessly like it does with iphone or macbook. Obviously, these should be solved with time no doubts.
