According to some people who have tested it, it is amazing to use it to watch a movie, watch a big screen and the 3D effect, the Vision Pro is just a television from the future.
Interesting that on that basis, $3500 is probably about on a par with a really nice OLED big-screen TV and surround sound system.
One person only though, not a shareable experience.
Like others, I'm waiting for this to come to a spectacles / sunglasses formfactor. An external box would be fine, I just wouldn't be able to bear wearing what looks like metal ski-goggles for any significant period of time.
