Now that you mentioned it, I'm pretty disappointed I didn't include it in the post! I greatly admire Tim Cook's stance on privacy, especially given the era where our personal information is up for sale. I myself haven't had the opportunity to purchase an Apple Watch, but I greatly look forward to the day that I do.
I got a feeling that there are a lot more tricks up Apple's sleeve when it comes to the health on the Apple device. Current measurements for diabetes and such are only the beginning.
