Re: Fitness: Yes. Smartwatches: No.
I keep wondering: Is there enough insight in this fitness data stream to be that interesting? I got a heart rate monitor for a present last year, and I wore it a few times biking, skiing, even shoveling snow, out of curiosity what levels I hit. But after a few times, the numbers were always about the same at the exertion level I was at, no real surprise. So I'll wear it once in awhile to see if anything's changing, or just out of workout boredom, but find there's nothing really to learn after the initial tryout.
