I believe that smart watches will become a huge market and only continue to grow. I believe that we will also see the development of other so called "smart devices," as well. As technology develops even further and allows us to pack more power into smaller devices the options become almost limitless on what could be created. I do believe that you are correct and smart watches are going to become a very profitable and growing niche market. Will they become the next wave of cell phones and mobile devices? That has yet to be seen, but there will be millions made in the market regardless of where it eventually leads.
