No one has been free to just “try it out“. There may be reviewers who are doing that right now, but the articles are certainly behind a embargo.
That said I don’t remember anyone saying anything other than that they came away extremely impressed. Which is why I’m really curious too.
Om Malik, for just one, has posted at least three articles discussing in depth his extended reviews of the Vision Pro. Here's one (https://om.co/2023/12/14/why-vision-pro-will-change-photogra...):
> Over the past few months, I have had the opportunity to spend time with Apple’s soon-to-be-released Vision Pro, a spatial computer that you wear on your face.
That’s all Apple has let the press have, at least publicly. I’m sure they’ll be getting their review units soon. But right now those two times are all we have discussions from.
Either way they’re under NDA so they won’t talk about it if they want to keep their developer account. They can say they went to one of the workshops and that’s basically it.
