I understand and it does seem plausible, but I just can't find anything to support your claim. If you had something you'd have linked it up by now. So I've gone from 'quite likely' to 'almost certain' that you pulled it out of your arse.Originally Posted by Bob Sanders

...and how do them perfectly charged, exchangeable batteries help you if there is no net?

here's apdf... never posted a pdf before so I don't know if this will work:

Sorry... doesn't work. How do you post a PDF???
as an attachment, just like a picture from your hard drive.

Not sure I understand the question??
You assume that they use the iPhones/Pads as communication devices. I have never been to Tibet or Nepal, but I doubt that they have a lot of cellphone towers there.

We're not talking about tibet (in fact it said right on that video "no carrier")... we're talking about Everest which DOES have towers.
Can't. It seems the file exceeds the website's size limit.
Let's see if this works.... I took a picture...
This is froma pdf by hilman-blateau on the effects of high altitudes on electronics (computers in particular)

OK, fair enough. The issue seems to be with panel seals failing and allowing moisture to ingress. However, this article is old (2004). Also, you do realize that the displays on the devices in question are, most likely, made by Samsung?

I assure you the physics of air pressure on enclosed vessels hasn't changed in centuries
Have you once heard me say anything about samsung being any better in this situation???Also, you do realize that the displays on the devices in question are, most likely, made by Samsung?
Sure, but technology does change. I appreciate the article and there's a lot of interesting stuff on that site, so thanks for the link. But it doesn't confirm that the potential-LCD issue is the reason why Apple specifies a 10k feet altitude limit. Again, I'm not saying you're wrong, but that doesn't make you right either.
The fact still remains that the (NAT GEO-funded) expedition will be taking Apple devices with them when they could have anything they wanted.

Well, to be honest, I'd assume, they only take that stuff with them, because Apple has injected a bit of extra cash into this endeavor. The results of this expedition might give Apple some hints in regards to their technology, but if it something goes wrong, I don't think we'll ever hear anything about the Apple part of the story again.

Hue... What's INSIDE the lcd screen has changed over the years... but the vessel itself has not. At the end of the day you're talking about the same thing now as you were ten years ago. Airplane technology has changed INCREDIBLY in the last 10 years, but what remains exactly the same are the air pressures it must fly through, the pressurized cabins, the stress cracks due to pressure differences... yadda yadda. There is no way around it. The ONLY thing (consumer level) lcd manufacturers can do to combat this make sure as little gas as possible gets into the works.
You said it yourself.... BACKUPS. They can take their kid's tin cans and string with them if they want.... as long as they have back up.The fact still remains that the (NAT GEO-funded) expedition will be taking Apple devices with them when they could have anything they wanted.
Could be. A tech industry friend of mine said Apple are notoriously tight-fisted though. Is it true?
I wondered about that... but couldn't find anything supporting it.
Depends on. If it helps them selling hardware, they are actually pretty generous.
They don't invest any money in India though to develop a pool of cheap programmers to undermine US jobs and salaries, like another computer pioneer did.

Nat Geo expeditions always have industry sponsors (mostly Canon and HP - first time I heard of Apple). The fact that the story showed up in Apple's hot news RSS feed leads to the thought that Apple has, besides free gadgets, some money invested into this adventure.

No, you can improve the seals. Just as aircraft manufactures do to make the fuselage less prone to breach and decompression. It's interesting that you bring up aircraft technology because planes become fatigued through pressurization cycles. One famous case was the Aloha jet which failed because it flew short-island hopping flights and was therefore subjected to more cycles than aircraft flying longer routes.

It turns out, if you read the conclusion of your article:
"Initial tests by PSI indicate no immediate failure of the LCD at 35,000 feet. This should indicate limited issues during early use. The LCD will most likely leak after repeated pressure cycles; however the number of cycles required for failure is unknown and could exceed the expected lifetime."

Hue...
ONCE AGAIN
It all depends COMPLETELY how well the lcd screens are made. In the example I sited a while back, a guy took 2 iphones above 10,000 feet. One started to fail and one didn't. Now what part of this are you not getting???
And yes... I've seen the jet in question MANY times on a show called MAYDAY which I like to watch. The physics of aircraft and what they have to endure HAS NOT CHANGED

And this here they're talking about PERMANENT failure. There is such a thing on lcd screens where you get TEMPORARY failure. The pressure distorts the vessel till the lcd becomes unreadable. When the pressure returns to normal so does the screen.
Can you provide support for this claim? My apologies if it's in the article, maybe I missed that bit?

It states it guy's post who took the 2 cell phones up.
https://discussions.apple.com/message/7877266#7877266When I returned to Santiago yesterday evening, I was about to write a post on how I had ruined my iPhone, when I noticed that the spider pattern had vanished! There were literally two pixels that were black and the rest were normal again, this persisted no matter what was showing on the screen, using the app "flashlight" made this clear. The following morning, both those pixels were back to normal
But you can demonstrate for yourself. Put your finger on your monitor and lightly press it and watch the distortions take place under your finger pressure. This happens because the lcd is pressure sensitive. The same thing happens at altitude but in the opposite direction. Instead of the vessel being pushed in it gets expanded outwards. The voids created start looking black.
