To call the Apple Watch polarizing is to do the splenetic depths of online argument around it an injustice. For the past few weeks I’ve been living in the eye of that storm, the contentious wearable on my wrist. I’ve worked with it. I’ve traveled with it. I’ve exercised with it. I drew the line at showering with it, though Tim Cook says that’s okay too. And all along the way - well, perhaps not in the shower - people have asked me that one question no other Apple product has faced to quite the same extent: is the Apple Watch really worth it?
