Apart from the normal price, you could pay $1,100 and $10,000 for a Series 0 too if you went for premium bands for example. The vision doesn't offer a cheaper price just yet but it makes sense given that it's a 100% premium product right now, there is no possible downgrade because it really needs to contain the hardware of a MacBook and 2 high resolution screens.

I think Apple is planning this out over a really long time. The Apple Watch also started as somewhat of a novelty to check your notifications and steps - until they brought third party app support, bigger screens etc.
Initially Apple also said the average interaction with the Watch would be something like 7 seconds, now we are endorsed to scroll through our stack for minutes because the Watch developed that way. I see the same happening with the Vision. Starting of as a really clunky product with the goal to obtain real world user feedback etc. to gradually smart things down until it's pretty much a pair of glasses
I wouldn't wear this in public right now but maybe at home. Maybe in 10 years time it's normal to wear this in public too because it's just like a normal pair of glasses - but in order to get there, they need to get out the clunky version at first
I wouldn't mind if that extended to phones as well. I'd happily have a phone 3mm thicker if that meant double the battery capacity
