I just got the Fitbit One, and I'm very excited to see how many steps I take at work each day and how I sleep in the short hours that I do. I've taken care of syncing it to my MFP account already. My question is- I've been relying on my HRM for calorie counts during workouts. Should this now replace my HRM? Have you found it to have the same accuracy? If I wear both at the same time, will they interfere with each other? Sorry for the barrage of questions, I'm very excited to use my new toy
