Wow, that's an astonishing improvement in weight compared to other VR headsets. Here's Meta's line-up for comparison: https://i.imgur.com/JoTt10p.png
That said, lightweight is awesome. I think getting weight out of the headset is going to be really important for any sort of casual use of VR, but I don't think this product is good example of that, just because of all the other requirements.
I have a very mild interest in VR but if the tech really improves this is something I could try. Past experiences have been disappointing.
The last chances of a truly privacy-respecting VR experience dried up when "The Industry" walked away from OpenXR and other efforts to treat VR like a first-class technology and not a toy. Maybe not the worst choice in hindsight, but it's also the one that lead us down this road of "product-ized" virtual reality.
