I remember being rather skeptical of Apple’s original marketing of the Apple Watch as “our most personal device ever”, but a year later I must say that it would be a hard case to make that something that has been physically attached to me for 83% of my life is anything other than personal.
Thankfully, David is someone that will dig into numbers. In this case, it's seeing how many hours a day he's worn his Apple Watch since first putting it on a year ago. I know I'd love to see what my numbers reveal. Since using Sleep++, I'm sure I'm in the 20+ hours a day category.
