Tech accessories that don&#x27;t play nicely with established human rules of etiquette have a <i>much</i> harder time being accepted, that&#x27;s my theory. There&#x27;s a long established history of reading or writing in public, and smartphones play nicely with all the etiquette that governs these activities in public.<p>Watches have etiquette too, primarily, it is seen as rude to check your while interacting with other people. So basically an apple watch is a device that you can&#x27;t use in most of the situations where it would prove useful.<p>At the end of the day, where tech accessories are concerned, human social interactions are evolving much more slowly than the technology itself, and designers don&#x27;t seem to really take this into account. Bluetooth headsets and Google Glass are two more great examples of what seems to be a failure to account for social rules and norms when they were designed.
