So every single PC or computer manufacturer can use modular RAM. Including servers, workstations, data centers, super computers. 

But somehow the Apple chips cannot and are trying to convince us that it is not just plain & simple greed??

Where do I plug RAM into my iPad? iPhone?

Yeah, not a greed thing. It’s an architecture thing. One line of extremely high performing chips for their product line is just smart. 

Charging $200 for an 8GB RAM upgrade is not a "greed thing"?  Charging $200 for a 256GB SSD upgrade is not a "greed thing"?  Those are up to 10X the cost a PC user with modular upgrades pays.  It most certainly is part greed.  But then, Apple couldn't make that $3T valuation, could they?

The SSD prices are a bit steep, true, but you can simply plug in more storage.

The RAM "upgrade" prices are a different story because it's not simply "just plug in more RAM chips". Prices scale with volume. Low volume higher cost. High volume lower cost. Apple produces X amount of M1-8GB and Y amount of M1-16GB SoC's. DRAM prices are dirt cheap because those components are produced in the 100's of millions. Apple may only produce 10 million M1-16GB. That's the cost of customization versus commoditization.

I would assume the issue of eye tracking being more error prone has more to do with the implementation of the eye tracking system and just how accurate it is. From what I've heard, Apple's implementation is extremely accurate. So maybe Apple has been able to fine tune it beyond what the researchers were using?

And here is a major reason why this technology will not be replacing any current devices anytime soon.

Not sure how you came to that conclusion? Do you think it's a good idea to blindly walk around while inside a fully immersive VR world?

Have you seen all the YouTube videos?

Furthermore, this is not a limitation of the technology or device, it's a limitation Apple is currently putting on software.

I predict the iPhone will sooner that later have stereoscopic lenses to help drive the VisionOS devices that are coming.  It might not be the 15 but by the time the 16 rolls out I'd wager it will.  Most likely this will be limited to the high end iPhones.

Might make more sense to introduce a stereoscopic camera system on the iPad Pro first. It was first with a LiDAR Scanner as well.

Genuinely curious, why not include higher capacity memory modules if there's demand for it? I imagine the pin outs are the same for every capacity Apple uses, so why not include more than 192 GB for those tasks that demand greater amounts of memory? Or are M Series chips unable to address that much memory?

Are you sure they don't already use the highest density memory chips (considering size constraints) on those packages!? They need 8 (24GB) chips to achieve that 800GB/s bandwidth (1 chip per 100GB/s controller). Another thing to consider is the amount of power drawn by the increase in memory. Having that much power draw in such a relatively small area might be limiting.

With the M2 Max topping out at 96GB (4x 24GB), I'm thinking the 24GB chips they're currently using are probably the highest capacity chips they could fit in the given area.
