I have been using the bit less than $17,000 Apple Watch Sport the last few weeks. It certainly is not a necessity at this point like a phone, but it is a great add on. Getting a gentle tap to let you know you have a message or a meeting has already saved me a few times on things I would have delayed. The key is setting it up so you get the right number of taps. For example, the first thing I made sure was off was not getting alerts and taps for incoming email.
