Curious those who bought it a few weeks to a month ago... are you still using daily and how?

I am. It has essentially become my favorite computer for general "puttering" -- watching content, light browsing, messaging. Whereas before maybe I'd curl up with my mac in my lap in bed, or doom scroll on my phone, I now use it, and it is far more enjoyable and comfortable. For FOCUSED work at my job, where I really want no distractions and to just stare at something for a while and work deeply on it, it has been ni…

cool and have you previously used VR headsets prior and frequently too?

Im interest in developing bunch of ideas for it and as soon as it shrinks down to glasses size and or close ...it or one of it's competitors becomes the next iPhone.

Meta Ray Ban's seem to be selling well and all they do is reliably and solidly take pics and live video. A dataset to show people want smart glasses as well how many people in the world wear some type of form of glasses and also like taking pictures? I love my Meta Ray Ban's i bought in October.

> He didn't say this. Wired, however, did. If you go to the source, Apple/Jobs took accountability. But Wired got clicks. I think you got most of this wrong. The "you're holding it wrong" meme started on MacRumors, not Wired. MacRumors forum user samcraig emailed Steve Jobs about the low signal issue he (and many others) experienced while holding the new iPhone 4 in a specific way. He asked "Question - What's going t…

Apple has (wrongly, IMHO) gotten a lot of flack over this. People forget that at the time, there were a number images circulating around from instruction manuals for Nokia and BlackBerry phones that explicitly mentioned the same thing.

Yes and I felt Apple also wrongly got *flak about down-tuning some CPU performance settings when batteries start getting older. The same year that story went crazy, I had a Samsung Galaxy with a fairly used battery. Once it reached 25% capacity or so, it could still chug along fine for another several hours if you didn't do anything CPU-intensive. But drawing too much current from the battery (video/games/etc) would steeply drop the output voltage of the battery, and result in the phone instantly shutting off entirely. It was unlikely to successfully boot after that, because the boot sequence had a short stage that hit nearly 100% CPU utilization before power management kicked in.

Note that "25% capacity" is usually calculated from steady-state output voltage. The voltage of a battery generally drops slowly as it gets used. But when the battery gets older and its internal resistance increases, it can no longer output the same current at lower voltages. The energy is still there, but can only be accessed either by sipping it slowly for a long time at a useful voltage, or pulling the energy out quickly at a uselessly low voltage.

So two solutions could be: Let peoples phones randomly die sometimes at 20% charge. Or set 25% to "0%" and never let anyone use those extra few hours for idle texting/etc. Or throttle the CPU after the battery falls below 50% so the phone can't cause fatal battery voltage drops with short bursts of high CPU utilization.

I thought Apple made the right choice for consumers, it's the solution I would have wanted on my Samsung, and I was jealous iPhone users didn't have to deal with a phone that said "25% full" but could randomly shut off at any moment in your pocket or hand without warning.

*I believe it is flak, not flack.

>> 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…

> The device was being charged

The external battery pack is the only battery, there is no internal one being charged. There is also no mention of the external battery being charged.

Polycarbonate is better in some ways but more susceptible to scratches than plexiglass. Glass is great because unlike the plastics it is UV resistant.

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.

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.

Fair enough; good to know.

Have had several VR headsets, ranging from a Vuzix way back in the day to the Valve Index and Q3. This is the first one where I have actively OPTED to use for something other than gaming. The one thing I’ll knock is that other devices I’ve owned have been more comfortable (notably the Valve Index, which out of the box has had the best comfort of any device I’ve had, although I cannot use it lying down/on the couch because the head strap is so bulky).

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

It's not a warranty, It's that the seller is responsible for any manufacturing defects, and in the first 12 months(6 months in the UK) any defect is presumed to be a manufacturing defect automatically unless the seller can prove otherwise.

After that time the seller is actually responsible for 6 years after the original sale, but the responsibility is on the buyer to demonstrate that a fault is a manufacturing defect.
