If Apple can't do wearables, who can?

As we all know, the idea of wearables is very topical, but not selling well. All Androidwear watches combined only sold 720,000 watches last year. (Full disclosure, I like mine). Now we have news out of Apple that its most hyped feature isn't going to happen. The watch was supposed to check our blood pressure and the oxygen in our blood and even our stress level. These are important measures of health. Apple announced that it is apparently too difficult, at least with today's technology. More advanced features, like glucose detection had not even been planned (admittedly, no one has reliably accomplished that yet). Does this spell the death of wearables? Probably not, they may just be farther out than we would like. Personally, I believe that real-time monitoring of your health is a big part of our future. Apple's simple design seemed great, and of particular interest to their customer base. I guess the time has not yet come. Unless Samsung beats them to it.
