This kind of post is just a rehash of the traditional talking points about Apple...
Yes, there were personal computers before the Apple ][ and the Mac
Yes, there were mp3 players before the iPod
Yes, there were smartphones before the iPhone
Yes, there were tablets before the iPad
Yes, there are now smart watches before the rumored iWatch
The difference, of course, is that NOBODY actually bought this stuff until Apple perfected the design, features, and ease-of-use part. Once shown how to do it by Apple the so-called competition jumped in. The smartwatch market will be exactly the same.
