With the release of the Apple Watch SDK, we finally get a clearer idea of Apple's wearable future. They released a huge torrent of information with the SDK and an introductory video above (excuse the ads, it's an embed from Theverge.com). You can check out all the official information provided by Apple at https://developer.apple.com/watchkit/ as well as the developers programming guide.
I think Apple is the only market player which can truly kick off the wearables era. That being said, there is still a pretty big chance they'll fail to get traction; much like the rest of the tech industry. Let's see where they take us.
