I am a small business owner, so a smart phone is a must. Like it or not, a lot of business is done through texts and emails these days. Likewise, the mobile card reader is just as important. As for a smart watch, I got one of those recently. I run and swim as well. I needed a heart monitor and didn't want a strap. I don't have heart problems. When I hit a certain level of physical exertion on the bike or running my nose will start bleeding like clockwork. Clockwork, Smart watch, is that a pun? So, I got the watch to stay right under the "redline." The watch can also monitor sleeping habits. That is helpful, but I already know I need more. The watch connects to fitness apps, but I'm not much of a data type. For a number cruncher though, it is a valuable tool.
