Apple Watch is often oversimplified as an iPhone on your wrist, and almost everyone I have demoed it to has accidentally referred to it as "your phone" - even I slipped up once or twice in the last year.
Its not an unreasonable comparison. The square-shaped smartwatch is like a mini iPhone; it enables me to read emails, summon Siri and make and receive phone calls from my wrist.
The size is just right too. While many Android Wear watches look and feel chunky to the average person I talk to, the 42mm Apple Watch fits my wrist much more unobtrusively.
An even smaller 38mm size is also available, although most people should for opt for the bigger of the two. It offers better battery life and more useable touchscreen space(but does come at a slightly higher cost).
What feels strange about writing this review is that theres no point in really comparing it to Android Wear at all. Nobody chooses a smartwatch first and then decides on which phone to go with it; no, if youre reading this, youre probably either scanning through my review on the iPhone or with one close to hand, wondering if it adds enough convenience to make it worth the extra cost.
