Hell, I won't even use digital thermometers out of concern that they'll upload my body temperature to the internet. I'm not going to be uploading my vitals to some app developer in Mencino.
Honestly, I think we're seeing late-stage Apple at this point. Each new product announcement makes a smaller and smaller blip on the radar, and Apple is entirely a company whose fortunes are tied to the faddish vitality of a brand name. Every year Apple does less and less to differentiate itself, and their older products are starting to whither a bit. The people who were excited about OSX 16 years ago have less and less to be excited about with each passing year and those aren't the same people who are going to get excited over a watch or something that will tell them they need to exercise more.
I'm not saying Apple is going to crash and burn or disappear, but when a company's capitalization is their biggest news don't make the mistake of thinking the future is a foregone conclusion. (see: IBM).
