Weird. JerryRigEverything showed that the cover glass is actually plastic. It's got way too low scratch resistance to be glass. And plastic shouldn't crack like this. Maybe only the top layer is plastic?

not accurate. the cover glass is wrapped in plastic. it's a glass sandwich with plastic as the bread. it is glass.

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.

Well, you probably didn't read Apple's instructions then :-)

Steve Jobs would have responded with "you're wearing it wrong."

He didn't say this. Wired, however, did. If you go to the source, Apple/Jobs took accountability. But Wired got clicks.

You're seriously going to quibble about "Just avoid holding it in that way." v. "You're holding it wrong." That's some petty shit right there. I suppose not surprising with how this forum has deteriorated over the last decade or so.

Now we know why Apple does not sell to EU yet, where there is a 6 month warranty by law for most goods.

Why would that matter in this case? Apple has a 12 month warranty on this and most of their other hardware. Also, I expect most people shelling out $3500 for a headset are going to get AppleCare+ which also covers accidental damage.

AppleCare users are paying hundreds of dollars for this fix.

Ah I see. But I wonder why they went for this. Why put the most scratch-sensitive material right on the outside? This way you get all the negative sides of glass (high weight, cracking under pressue or impact) while you get none of the benefits (scratch-resistance).

And in this case the side of the material that's exposed to the user is plastic. Why would Apple brag about it being glass if the user can't even notice it? :)

are you a bot? you seem like a bot. I've been watching you and you're very bot-like. tell me otherwise.

You are entitled to your opinion. I don't have the time nor the will to engage with your concerns.

Earlier quoted context omitted.

Polycarbonate is great for UV resistance, though not sure that matters for something you use indoors. I’ll grant you scratch-prone. There are additives and coatings for everything now, and the glass Apple is using is also highly engineered so you can get just what you want no matter what. I’ll bet it comes down to feel and consumer experience.

Only with a UV film installed to protect it. I think all plastics degrade under UV light and polycarbonate is no different. It will yellow and lose it's strength with unprotected UV exposure.

Not so. Sure, everything degrades eventually, but HDPE, PC and acrylic are notably UV resistant, and even polypropylene, which is normally weak in UV, is used in outdoor furniture. Thickness and color matter, but inexpensive UV stabilizers can be added to most plastics as well, and you can get a guaranteed 7-10 years of outdoor life, let alone the sheltered life of a Vision Pro. Source: I make plastic products (sorry, world, that’s why I care about making them well).

Anyway, additives or coating, we agree one can get good outdoor performance with plastics. But forget glass, I’m waiting for the sapphire Vision Edition.

Correct

> Maybe no surprise to Apple It would be a huge surprise for Apple if a lithium battery inside the visor caused the cracks, as they did not design the head unit to include any internal battery.

There isn't a significant battery inside the visor. Unplug the external battery pack you keep in your pocket and see what happens.

I would need someone else to tell me because I'm not buying a $3,000 toy.
