Very good
In that I completely agree that all this monitoring stuff is going to be just as big a gimmick as 3D was/is for tellies. As always, the industry is looking for an idea to pinch, unfortunately companies such as Samsung have never had an original idea and are therefore utterly dependent on Apple/Google to come up with something.
The same thing goes for those so called-smart watches. When all they do is tell me my phone is trying to tell me something, what exactly is the point? The problem is that the physical dimensions are too small to allow for anything useful: you can't fit a proper display there, speakers are a problem, battery life will be horrible, never mind about having a device emitting all kinds of signals and radiation on your wrist every day...
If anyone can make it work it will be like the iPod Shuffle all over again. No display (or very rudimentary) but with a novel way of communicating. Maybe the watch will tap on your wrist to inform you of something.
For those of you who haven't yet seen it I recommend watching "Her". It's the only film which realistically portrays what a next-gen interface could look (sound) like.
