> The FitBit could go for 10 days, but I would have to monitor it (usually wait for the app to tell me) and then go find the charger and plug it in. Oddly the fact that I charge my watch every night seems like less of a cognitive burden to me because I don't actually have to think about it. I can agree that the fitbit is a little more fiddly in that regard, I sometimes get surprised when my charge is low. But one of the things that I love about the fitbit is that I can track my sleep - and I cannot do that if I've taken it off overnight to charge. I guess different people use their watches for different things. For me I like the step-tracking, love the heart-rate monitoring (when rock-climbing, lifting weights, or cycling), and adore the sleep tracking. I only have a single complaint, and that is that the thing isn't waterproof. If I could go swimming with it on I'd be a complete satisfied user.
