"It may be a difference in temperament. But personally, I like to reduce things in my life which require any form of attention: because I forget things very easily (or am just too lazy to do them)."
That was exactly my primary concern. In practice though, you (well, I, and most people) charge my phone at night. I set it next to the bed and plug it in... now my watch charger is right next to my phone charger, so its a no-brainer (and the wristband is fast on/off - thats important to me). Turns out because of the phone, i had no new habit to get into :)
I don't think this is accurate. Someone brought up a comparison of smartphone to a Nokia phone, but this is not the same kind of comparison. A smartphone greatly simplified user interface and made accessing the internet and sharing much easier, and also created new ways of interacting (swiping etc). Whereas, the watch seems to be very featureful sure, but the internet is already accessible using your phone. And the added worry of carrying yet another charger when traveling (and the horror of losing it...). Now, a traditional watch, you don't worry about it for YEARS, not a week. Its mostly another ornament, like a cap or a shirt.

Also, this may not apply to everyone, but there is simply too many beautifully crafted wristwatches out there for me to ever seriously consider a smartwatch.
