Yes, make the battery 2x bigger and include the compute in that.

It would be so cool to be able to plug in arbitrary input devices too, like a dvd player, but its understandable that others don’t feel this way, and it would totally not be an apple product if it did this.

One of their main imposed constraints was clearly to make the battery pocketable, which sadly precludes a lot of things which would have made it a better product, in favour of wider acceptability.

You can't move the compute away in a headset. I have worked for an XR OEM, and when you are designing a headset, you want the compute to be as close as possible from the cameras and displays, to achieve the lowest possible latency and avoid motion sickness for the users.

Even moving the compute to the back of the headset was not considered viable by our HW team. And we haven't spoken about the bandwidth required for all those cameras and UHD displays.

A better way to reduce the weight of the AVP would have been to remove the (useless IMO) front holographic screen, and to replace most of the glass and metal by plastic. And maybe move the battery pack to the back, to get a more balanced headset.

Meta has shown pretty convincingly that you can literally stream VR apps/games over Wifi from a PC to a headset and have a great experience. You will need some compute on the device, as close as possible, but the bulk of the computing could be moved off.

Have you ever tried that? For me, the lag was the tiniest bit perceptible and was enough to make me sick

Light would travel six feet on a cable in about 10 nanoseconds, is that the sort of latency that you're referencing?

I would be surprised to learn that nanoseconds of latency is worth more than much better compute, lower cost, lighter weight, more physical space in the device etc.

Is that really the case?

The Big Screen Beyond and WiFi-enabled video streaming like for the Quest 3 and upcoming Steam Frame disagree with you.

I agree w/ most of what you said about reducing latency.

Just wanted to let you know the new Dual Knit bands are weighted in the back, and improve the balance a bunch.

Considering the short battery life, I’d prefer they ditch the battery and just tether the headset completely. Maybe have a small internal battery just to facilitate a 5 minute change of input.
