Will they stand up to longterm daily use and abuse without compromise, and find public acceptance? Who knows. I haven't been craving one, though I'm always open to new ideas.
That's the million $ question. I have played with the Android/Sansung version at BB and on those demos you can tell where the fold is. You can see it for sure and I wonder over time if you will be able to feel it as well.
seems to me that a foldable iPad solves a problem, but a foldable phone does not. Who wants a double-thick device that is supposed to go in your pocket?A poster at MR suggested this might be a testbed for a foldable iPhone. Does that make sense? Would it be easier to make a foldable iPad and/or would the iPad need less durability (less open-close cycles per day)?
Well, that's a different question from the one I raised. As to yours, a foldable phone absolutely solves a problem, if they use use the folding feature to make exising phones smaller, rather than to offer larger phonesseems to me that a foldable iPad solves a problem, but a foldable phone does not.

I just don’t see how you don’t end up essentially twice as thick. Battery has to go somewhere, and you need volume to cool the chips.Well, that's a different question from the one I raised.

Specifically: My wallet is 115 mm x 85 mm x 20 mm, and comfortably fits in my front pocket. An iPhone 14 Pro, and certainly a Pro Max, like most smart phones, is too long to do so comfortably (especially when you're sitting down). However, folding an iPhone 14 Pro Max in half makes it 80+ mm x 78 mm x 16+ mm—even more compact. And if we folded an iPhone 14, that would be even better: 74+ mm x 72 mm x 16+ mm. [I added a plus to the long dimension to allow for the hinge, and to the thickness b/c I don't know if it can be made to fold perfectly flat.]
I personally think having a smartphone that you can comfortably carry in your front pocket is a BFD.
Sure, but the 16+ mm figure I gave already accounts for the doubling of thickness, since the iPhone Pro's are 7.85 mm. And, as I mentioned, that's still thinner than my ~20 mm thick wallet, as well as having a smaller L & W.I just don’t see how you don’t end up essentially twice as thick. Battery has to go somewhere, and you need volume to cool the chips.
Not quite following--are you saying to embed the lens into the edge of the device? That would require a tiny lens and sensor. The small lens would limit light-gathering, and the small sensor would limit PQ. But not sure if you meant that, since it could be done with a slab phone as well.In looking at theorist9's graphic, it occurs to me that there could be an additional advantage to be had, depending on the design implementation: the camera could go into the top (or bottom edge), eliminating the camera bump while also putting paid to all those goddam 9x16 videos. (A lens does not actually have to be a big circle, and longer focal length tends to provide better quality – embedded lengthwise could offer longer focal length without the bump.)

Imagine if they put all the works in proper balance behind the screen and supplied a detachable keyboard with a wide tab that holds the keyboard and flips out underneath when you pull the keyboard down. The tab would extend back horizontally to give the screen a resting surface on your lap (or desk, with or without the keyboard). It would be the Surface, only done right (a horizontal brace rather than a vertical one).And if they come out with some sort of “folio keyboard” type contraption for it, that would be more than enough for me.
1) Interesting. Can you cite any examples of non-orthogonal CCD's? And what's the angle limit? It it enough to allow the sensor for the iPhone 14's main camera be angled sideways within the case? Samsung uses something similar to what you describe to get a long focal length—a periscope camera*— but that's with an orthogonal sensor. And that obviously wouldn't work for wide-angle cameras, which need the sensor to be close to the lens.It is what I meant. CCDs are very small, and unlike film, you could easily design them to function well in an orientation that is not orthogonal to the light stream (that is, at at angle), which would provide comparable picture quality while also mitigating the reduced light concern.
But I would only consider that arrangement for a phone. For a tablet, I think the (sole) camera should lie in a trough on the side, with a mirror on the end to allow Q&D facetime, but for taking pictures (or lengthy FT calls) you lift it out on its tiny gooseneck and aim the camera instead of trying to aim the whole tablet.
It's amusing to think that a 21" foldable laptop is essentially a portable small iMac (older model).Looks like it may actually be a Mac?

That's generally true, because most lens designs are refraction-based, but you can mix lenses with mirrors to create very compact optical designs with long focal lengths. See for example, Nikon's Nikkor 500m f/8 reflex lens. Simple reflex lens designs typically have small aperture sizes though, so probably not suitable for phones as-is. Bokeh is also donut-shaped on those lenses, but that's not a phone since on a phone the lenses have a very long depth of field. Also the aperture is often fixed, but that's not a problem because cameras in phones have fixed aperture sizes anyway.Since the telephoto camera on iPhones is not folded, the phone's thickness limits the physical length of the lens, and the only way to give a lens a long focal length while keeping it short is by using a small sensor.

Since no one has brought reflex lenses back, I guess they're not practical on phones either, but I wouldn't say that keeping telephoto lenses small is outright impossible.
