The Vision Pro is marketed as a device with the potential to replace or significantly augment a laptop and/or TV for a lot of users (I understand there are presently some asterisks needed there). And that's assuming no other novel, high value uses emerge.
Apple sells something like 7 million MacBooks per quarter. Many of them are well more than $2000. I don't think a $2,000 price point is a crazy barrier if the device is able to live up to what it could be.
