In the US, smartphone and tablet displays have replaced the TV set as screen number one. Meanwhile, not only the time spent on mobile devices has become longer on mobile than on the tube -primarily the intensity of using mobiles, the attention, people dedicate to mobile content, is higher.
Smartphones and tablets have thus become the first screen.
Nevertheless, there are plenty of occasions, when a smartphone is out of place, or even annoying: At the table, during a lively conversation, or while driving a car, to name just three obvious examples. My twitter friend Jürgen Geuter has put it in one sentence, why smartwatches will the remedy here: To check the wrist watch is socially accepted. Completely within the common boundaries we may just look on our smartwatch if the awaited reply on Whatsapp has arrived, just as we would have consulted the watch to get the time. Likewise, smartwatches are handy in the sense of the word, when we drive a car, and in combination with speech recognition many smartphone apps will work even better than the hands-free kit.
Smartwatches will thus become the second screen, the companion of our smartphones. Also therefore they will find their buyers.
