Because computing is now part of everyday lifestyle.
If you think from your customer's point of view; having a website, app or other computing services matter only if they all are in sync. Going forward, you need to ensure that the information is semless between website to smart watch. Becuase using a device is only a medium so developing a solution for only one platform will not do the trick for your clients.
Remember, computing devices are helping your business grow so ensure you are helping your clients with all platforms. You have to move on to the next platform before your customers do, else you will not be able to leave your mark.
