Smartwatches are accessories to your cell phones.
Telling time, alerting you about calls, emails, texts and appointments
without the need to reach into your pocket
(as some people do more than 100 times a day according to a study)

Today's smartwatches also run many useful apps like:
music/headphone controllers, camera remote viewfinders,
healt trackers for steps, movement and sleep patterns,
weather information display and phone finders.
All things your regular watch does not do.

Who is going to be next: Google, Samsung or the Fruit company?
