Spend more money on AirPods Pro. Download an app called Cinephile, lie in bed, stream Star Wars Andor in 4k on a 100ft movie screen. Then tell me that you are still sad.
There is no doubt this is expensive, but I compared it to the cost and space consumption of very large screen TVs or 4k laser projectors. Its a great choice if you don't have a place to build a (good) home theater and don't want to run wires everywhere. Its well suited to people who travel a lot, or live alone, or perhaps are stuck in senior assisted living/military barrack/container ship, etc. where it could enhance your free time.
I don't think any VR device on the market is going to be a mainstream product due to weight and expense (in that order). Apple Vision Pro is so far ahead of the other offerings that its the most likely to evolve into the mainstream product.
Apple still has room to improve the hardware in many ways. Most important is that its not high resolution enough to use as a second monitor for your laptop. Text is harder to read than on the laptop screen itself. This is a big disappointment. Also, the requirement to use iCloud keychain is a fail. iCloud anything is a fail. Other apps like Split Screen and Immersed are coming along though, they don't require iCloud.
The device is slightly heavy to be used as intended and it hurts the nose when worn by some people. The field of view is competitive but if it were wider, that would be great. The internal reflections on the optics is a small nuisance in certain apps like watching bright videos on a black background.
Apple will devote a lot of time to the software which is promising, amazing even, but unfinished. VisionOS could do so much more and needs refinement. Its not buggy, its just lacking a ton of things that you would expect to be there after using iOS.
Apple Vision Pro might be the most high tech consumer product that I've ever used. Its unquestionably amazing. There are numerous times (per day) when I laugh out loud at how incredible it is... the immersive environments like Hawaii and Yosemite, gimmicky apps that float 3D objects n front of you with photorealism, immersive video, video games on your ceiling, Inspaze (weird but intriguing).
Watching movies in bed where the weight is not a factor is a killer app. Its stunning. Immersive video is also stunning, but making an immersive video worthy of an Oscar is very hard. The best apps are definitely yet to come.
There still isn't enough software available to justify the expense for most people. Apple must know this because they are really pushing you to be inspired to use iPad apps. Apple is, perhaps wisely, devoting no space to AVP apps on the app store so that the media cannot attack them on this front. When the apps arrive, Apple will definitely have a very obvious AVP presence on the App Store.
If cost is not an issue for you, and you want an amazing home theater, definitely buy Apple Vision Pro and AirPods Pro.
