Having a device suddenly turn off can be an issue even with an internal battery. This should be something anyone using Vision Pro keeps in mind. And by that I mean don’t go driving in it, or model Casey Neistat and wear it while riding an electric skateboard in the middle of NYC streets. In normal situations, sitting in your home or on a plane, having it go black isn’t a big deal. Just take it off.

This is where AR will really shine, if/when we ever see true AR with similar image quality. Then if it turns off, it comes glasses and not a blindfold.

The same, especially the short concern, applies to the proprietary cable, no?

In general, it seems that the lack of a built-in energy storage (even if short-term, for 2-3 minutes) is an issue; for instance, it makes hot swapping of batteries very hard.

Yep. Same for the other end of the cable. I’ve heard folks ask why it doesn’t use a mag connector like on the Apple Watch since it appears to mimic the shape.

Are you sure about this? I heard someone answering that it stays on for a while so you can switch between battery and mains power. Not sure though.
