>> The reports all mention that the crack became visible suddenly and for no apparent reason, after the headsets had been connected to the external battery pack and stored overnight (some in Apple's Travel Case) with the soft front cover attached. It is glass. The device was being charged, which means some heat gradient between the charging battery and the outside world. That thin 3d-shaped glass cracks under thermal…

There's no battery behind that glass, so it's the processors or another component generating heat while stored.

It would never occur to me to store the device connected to its battery inside the case — or outside the case, for that matter. I don't like the idea of that dense, heavy battery potentially getting displaced from the holding strap in the case cover and banging around inside against the Vision Pro. Since I got mine February 2 I've kept both my batteries attached to chargers when not in use.

The Apple case has safe stowage for the battery. It is categorically not going to be banging around if you secure it in the case properly. I've taken mine to work frequently since release and have not observed it coming loose.

Earlier quoted context omitted.

Polycarbonate would be a better choice than plexiglass/acrylic. What advantages does glass have? More likely to break and more repairs?

scratches. its all about scratches. any poly will scratch pretty easily compared to glass, which is a bad thing when its a lens you are looking through. You could make the argument they could just design an easily replaceable poly lens at a reasonable price, but.....its 2024 device manufacturers hate the idea of any user replaceable parts.

You don't have to have a full cover.. Only the cameras would need to have a window of (sapphire)glass. The rest of the ski-mask could easily be plastic, as it's only used to display eyes.

My guess is that it gives them a few cycles to improve the weight. The iPhone X was a monster in terms of weight
