1. People use these GPS watches for Ironman triathlons, ultra running & cycling events etc. They can't and won't charge before the battery is done - and remember the battery with a daily charge will degrade significantly. If it's borderline on release, it'll be inadequate after a year.

2. Just for general convenience, having to take another special cable for every late night or overnight trip is maddening. I always have a phone anyway for any actual interactions.

I find it hard to believe many people are writing texts on their watches, it's just a nice to have gimmick feature that everyone I know has stopped using.
