While learning, testing, and evaluating my Apple Watch I wear it all hours of the day except for my work out and training routine each day.
Edit: I wear SUUNTO for training and competition.
While I'm finding the watch fun to learn, I am enjoying the differences. With a rather unintuitive UI, reading the manual and watching the videos were also fun. I love learning new things. Now that I have a very good grasp, it's fun but I don't plan to keep it unless it has some value to offer me.
Wanting to have the first hand experience, I bought it to try out and see for myself just how it measured up to Apples normal high level of hype. I'm not one to make any decision off others opinions, I'm glad I bought it and I won't decide till I give it a very fair chance to prove itself.
One question I do ask myself is... Will the unintuitive UI, plus requirement for an iPhone, and the other challenges facing a new user, caused them to ignore the Apple Watch... this ought to be very interesting.
