I agree with some of the other posters in the forum, Samsung is running on Apple rumors now. They heard that Apple may be working on an "iWatch" and what do they do? They release a smart watch. They hear that Apple may build health monitoring features into the "iWatch" and what do they do? They release another watch, within 5 months, that has a heart monitor feature.
It seems clear that Apple is working on products that include medical functions, but it would be really funny if it is not a smart watch, and Apple was feeding rumors to the competition to get them to chase their tails as Apple is preparing to shake up the landscape once again. I sense that Apple is not only working on a single product such as a watch, but is working on a whole ecosystem that they will release, that centers around medical sensors and other features that their current products don't offer. This new ecosystem will connect to iCloud, and will tie it all together.
