It's one more thing that makes it unlike a phone or a laptop with a long battery life. (Haven't had one of those since my netbook fell apart)

The Hololens 1 has the problem that it does not work outside in the day at all, it is just not bright enough to compete since it works by adding to (not subtracting from) light from the outside world. Inside the house though it can put "holograms" in all but the brightest places. No way I am installing Microsoft Streets & Trips on it and using it to navigate on foot or in the passenger seat of a car.

The Apple Vision will do better outside. For years I've been dreaming of making an Iron Man Halloween costume with a passthrough VR setup, even though I anticipate I'd need to have a handler to stay safe. I guess if I don't do it this year I won't get to do it before it becomes passe.
