2. My existing monitor is already really light on my neck.
I don't see any benefits.
2. Taking it with you easily. You have the same large screen (s) with you in the hotel room or at your in-law’s or at the cafe (people might look at you weird but this is a massive flex regardless)
The Index pretty much has it -- it's doable. I can read comfortably in there, or watch a youtube video and not feel like I'm getting some grainy, crappy version, but it's just barely there. It's very heavy and hot, though, so I almost never choose to use it.
The claimed resolution of the Vision Pro is unbelievably larger than the Index. I forget what the numbers were exactly, but they claimed to be able to virtualize "multiple 4k monitors" or something, and the per-eye resolutions _actually supported that_.
The next thing is: it's gotta be reasonably light, balanced, and cool, so I can wear it for an hour and not get intense neck pain or nausea. I'm skeptical but, hey, we gotta keep trying.
If it hits those points: it'll be a great virtual monitor and a lot more.
But they don’t have as compelling latency, hand tracking, or app development toolkits
