Early reports are that the Vision feels quite heavy to wear. That’s almost certainly going to make it a bad choice for virtual screens for more than an hour or so.
But on the other hand, they took the feedback this time and created a different strap to address it (and early reviews seem to indicate it does help quite a bit).
So - lols aside - I don’t think it’s quite the same thing. I think they realize it’s a real issue for some people and they’re trying to address that earnestly.
If I can wear that while being physical I can probably handle the Vision Pro for extended periods.
The Quest 2 wasn’t that comfortable to use out of the box, but after adding a Vive Deluxe Audio Strap connected with 3D printed adapters (which distributes weight better) and a counterweight that’s attached the back of the strap it’s dramatically improved. Still not perfect, but I have no issues wearing it for an hour or longer playing Beat Saber.
But I just don't think weight alone will be a concern given my experience with the Index.
My only problems with the index is the weight distribution while moving around (particularly while playing beat saber and crouching) but I likely wouldn't be doing that with the Vision Pro. And heat while being physically active but that was easily solvable by adding a fan to the front.
I already use this thing almost every day. But maybe that's because I am used too it so the jump to something like this is not really that crazy.
