I think the problem is making the software intuitive and compatible with existing computing. There are plenty of virtual screen/limited AR glasses that are much smaller than the vision pro and even VR headsets much smaller and lighter (for tethered use mostly). But I have no interest in moving my life over to the Meta's operating system. I want my decades of safari bookmarks and my iMessage, I want to seamlessly use my headset to extend my Mac's display with no fuss, and all the other Apple ecosystem benefits. That, or something so clearly capable and better that I can scrap all my Apple devices to jump ship completely. VisionOS seems like a killer app on it's own, but as security it also interfaces with the rest of my digital life so I don't have to dive headfirst off a cliff without checking if there's water or rocks below.
VisionPro might be the "best" hardware out there in 2024, but that's honestly incidental. I'm not sure I've ever bought apple gear because of the hardware specs vs other manufactures, but because my family and k-12 school both used macs, so by the time I was making my own decisions hardware wise I wanted to stay with what I knew. It's like religion. Almost no one chooses a faith, they just get used to going (or not going) to one church and it would take a lot to make switching feel worth it. Apple tests my limits regularly, but swapping away from apple for good would cost me thousands in hardware and untold misery in learning totally new software to do things that are second nature on iOS/WatchOS/iPadOS/MacOS.
I'll buy VisionPro over something like Nreal glasses even at 10x the cost, because I trust it will actually work the way I expect it to. I trust it won't be wonky and buggy and rely on hacks to kinda work with my apple devices, but that I'll be able to glance at my Mac, snap my fingers and open up files from my desktop right in front of my face. Because I know I'll be able to receive and respond to iMessages, to have my pinned conversations and my favorite phone numbers right where I left them. To open up a browser and continue reading the same website I was just looking at on my phone, etc.
VisionOS seems like a great product on it own. And VisionPro seems like some impressive hardware, but if all else fails, the Vision product is the AR for me because at the very least I expect it to work seamlessly with my half dozen other apple devices, not sit on a shelf because figuring out how to benefit my work or play is too much work to be worth it.
Point being, Practical AR is a software problem not a hardware one. I have confidence in Apple because of their software, not their hardware. (in all honesty, software being equal, I don't know if I'd own any Apple hardware at this point. If there was another full spectrum ecosystem out there I might be willing to try it, but Android + another flavor of Android for tablets + windows or Linux + maybe a fitbit app or something to sync with a watch + constantly manually pairing BT headphones when I switch devices .... it's just not feasible to switch from "everything works together" to a bunch of half baked, buggy solutions to kinda bridge two totally different software packages. And that's why I haven't bought a VR headset yet. I'm only interested in it if it works seamlessly with my existing workflow. I've been dreaming and waiting for the AR revolution to fix so many frustrations with the world of 2D screen interfaces, but to be a solution, a new AR product has to augment or even replace my exisitng workflow, not exist seperately in parallel to it.
