I wonder, is the bandwidth not there to put all compute In addition to battery in external device and make headset half the size? I’m sure they considered this, would love a technical explanation. Maybe it wouldn’t be smaller?

The battery's already in an external device. I'm not sure if the compute part takes up all that much thickness? Just think of how thin your phone is, and much of it is battery.

  Cooling takes up space and weight, but wiring all cameras, screens and sensors to a compute box would also be clumsy, and using a single high speed link would add more parts, losses and needs for cooling, and then the external compute module would be not be pocketable...

It isn't intended to be tethered you can walk around with it on and they chose balance and durability over lower weight and size of the headset..

The battery is already external and the compute is a tiny fraction of the size and weight of the HMD. To make any meaningful difference in the form factor, we'd need an entirely new generation of as yet invented display and lens stack. Maybe that happens in the next decade or so but it hasn't yet happened over the last decade of tens of billions of dollars invested by the largest companies in the world.

  We have tethered headsets like the Bigscreen Beyond [0] that get a lot smaller than the AVP. We're talking a fourth of the weight for about half the volume. The per eye resolution is smaller (2560x2560 vs 3660x3200) but not enough for the lens and screen to be significantly different IMHO. Lack of eye tracking would be more impacting, but we could probably get away with only a slightly bigger bump somewhere ?
