I understand that they're getting to the point where you can charge just while showering, but aren't quite there yet.
I do like having a heart-rate tracker, but having had a couple of fitbits the novelty eventually wears off and the reality that knowing the numbers isn't important sets in.
Also, if my hands are full/dirty I can still control media playback (granted that using the nose to tap on a watch probably looks pretty funny), and have weather right on my wrist (which is surprisingly handy).
Edit: Also it turns out to be the best kind of alarm for me. Audio alarms are annoying (also to anyone else who has to hear it) and don't really tend to wake me up nicely. Turns out the slight vibration of the watch wakes me up pretty nicely without bothering people in other rooms.
For all other situations, I just have to stick the watch to the back of my phone to charge it, so don't even need to carry around a separate watch charger.
It’s never been an issue.
I can't sleep with a watch on at night, so I take it off and put it on its stand, which is the charger- my phone goes on it's charging stand at the same time.
