The case was made that a pop-up camera is objectively better than a flush, on the face camera.
I was offering obvious counter-arguments to that. Sure, some people may prefer the aesthetics of a pop-up camera, but that does not make it objectively superior. There are compromises to be made with a pop-up, those compromises are pretty clear, and the preference for one or the other is at least subjective, if not leaning towards the less risky option.
That's all.
I know this is personal for you, the whole notch thing (I've never seen someone so persistently and vociferously angry about an aesthetic feature), and therefore any comments that do not fully embrace the 'notch is evil' viewpoint are threatening or laughable (mine are apparently the latter). It doesn't need to be that way, though. You can see from the poll here, along with all the anecdotal evidence out there, that most people really don't care about the notch. If this is the hill you want to die on, that's fine, but these are the realities:
I don't doubt some future version of the iPhone will be notch-less, or notch-modified, but when they do it won't be because Apple suddenly figured out how to make a lens move up and down, it will be when the product designers feel like a different setup makes sense given all the various pros/cons, risk assessment, etc.
- A pop-up camera frees up space on the screen, it's true, a couple of ~1mm dots.
- A pop-up camera also introduces extra complexity and extra risk of failure (as discussed above).
- Apple could've done a pop-up camera. The reason they didn't is obviously not technical incompetence (suggesting otherwise is dishonest), it was a conscious decision.
- Most people honestly don't care.
I know this is personal for you, the whole popup camera thing.
Problems a popup camera solves that are generally created by a notch:
- Non edge-to-edge screen: it enables a complete and full edge-to-edge screen, maximizing the screen-to-body ratio. There has been a lawsuit against Apple for false advertising. The filing describes that the iPhone X has about 10% less screen area than advertised. This is due to the notch and the deadspace it creates.
- Asymmetrical screen: There is a defined top and bottom to the iPhone, and Apps are blocked from turning 180 degrees. When Jobs launched the iPhone, he pointed out there wasn't a wrong way to hold it. Now there is. There are also design and usability issues that arise from a notch. For instance, pinching and zooming a photo where the notch covers that part of the photo and the rest of the screen doesn't: the parts of the photo show within the left and right portion of the screen but otherwise covered by the notch. Or a fullscreen game that's full bleed: the notch covers content like a wart. Or tapping to go fullscreen on a video... the notch covers a section of the video. These kinds of things are glaring and absurd consequences of an asymmetrical screen. It's equally absurd on a TV, or watch, or computer monitor.
- Usable screen area significantly reduced under certain activities, and not just on the notch side. Surfing the Web in landscape mode, for instance, causes both the left and right side of the phone to have significant bands of deadspace. If Apple didn't do this, then one side (the notch) would cover content while the other side didn't. To make matters worse, it's hard to see where the content stops since it's white deadspace, rather than some border that shows the edges of the webpage (e.g., on a properly designed phone where the page hits the uniform and flush bezels/edges of the screen).
- Scratched camera and sensors: a popup camera protects sensors and cameras on the front by hiding these things. Daily use can grind exposed sensors and cameras under glass on the front of a device where the glass can be scratched. The notch on the iPhone houses all of the sensors and front-facing camera under glass that can be scratched and may, in certain circumstances, affect the fitness of these things.
- Spying: a popup camera securely hides the front facing camera when you're not using it, thereby protecting you from spyware.
Now, to your other comments. You erect strawmen for starters. Also, you cannot claim to know what most people think/want so you can't say most people honestly don't care. Additionally, you simply cannot claim that Apple could have done a popup camera but chose not to. You have no idea, unless you worked at Apple close to that project or you know someone who told you this. Also, Apple spent years working on the iPhone X. From what I've read, from the people I've spoken to, etc., there isn't sufficient evidence Apple considered a popup camera. I'm also unaware of any patent for a popup camera that has Apple's name on it: this typically happens when they're at least considering something.
Apple may consider a popup camera for a near future iPhone. We'll find out in time.
