Why's that? They can get the weight down to barely more than glasses, and with good pass through video and battery improvements... You'll be pretty unencumbered. Certainly not more encumbered than being glued to your laptop on a desk.
Well it's hard to debate fantasy products given the circularity: "if they create a product that avoids all these problems, then it won't be a problem!".
I've not used a laptop (or computer) at a desk for decades, I prefer lying down, which works really well.
I do wish there was something between a laptop and a phone though. Interfaces need to improve or innovate, but I don't think VR headsets are the answer. I haven't even touched on the nausea.
I don't think it's a circular argument. Bigscreen VR is already 127 grams. This is doable in the next decade I think. The question is if there's a better form factor than something you wear on your face.
Bigscreen VR appears to be an accessory that relies on an external device for compute and head tracking and power. As far as I can see it's basically just a tiny OLED display you strap to your face.
With AVP, Apple is taking a bet that the accessory nature of previous attempts is why this product category failed and so they're trying to embed the compute and make it wireless.
Unfortunately for utopian visions of VR goggles, we're running up against the limit on how small computers can be, so the idea of a standalone headset as light as Bigscreen VR is essentially science fiction at this point. Not to say it won't happen, but if that's what it'll take for this product category to take off then your optimism is misplaced.
Fair enough, but form factor is indeed the issue, even light devices have to seal off your face, and the inner ear issues surely have a lot to do with that isolation.
Perhaps something along the lines of zapping the back of the eyeballs with lasers is the answer.
