You know, I was upset about this at first but I've changed my mind. Why would you want to see anything more than your resting heart rate and heart rate during workouts?
I too am less upset, as a lot of the time you have no way of telling what you were doing when it was recorded..
But my resting heart rate while sitting at work is a very interesting thing to me as it relates to sickness/stress/caffeine use etc.
So given I had stellar battery life with 1.0, I for one would like an option of 1-5 minute sampling if I wanted to take the battery hit.
It would also help filter out the obviously dud readings - I often get readings that are 1/2 or double the correct value. I just recorded a 44 while sitting at my desk, the rest of the morning was around 88. With my level of health, 44 simply didn't happen.
