Apple

I had the original iPhone. it was $500, which is about what I paid for my original Razr ($400), but it did 1000x more. only in retrospect was it clunky and awkward to use— at the time, it was like magic! Everything else at the tie was far, far inferior. it did far more than anything else in it day than most people had ever seen, and it was so much easier to use. and, as far as functionality, that came quickly later. also, the edge network was just about as good as anything else, as not that many people even had access to 3G yet. but even $500 isn’t $4,000. that’s a huge leap and not really a solid comparison considering that the Vision Pro isn’t really a mobile device at all— it’s a VR Mac with a full-on M2 chip and an R1 co-processor for all the VR stuff.

But, even considering the high-end optics and so on, it should only cost about $2k-$2,500 before offering processor and memory upgrades based on the pricing of their other Macs.

edit: for $4k, it should have an M3 Pro, 64GB of RAM and 2TB of storage.
