I think the lack of a AppleVision non-pro that was just some really good screens and a battery, hooked up to your iPhone/MBA/MBP for use as an immersive display was a miss. I tried the AVP but realized I didn't want/need to strap a Macbook to my face: I have a computing device, I just wanted the display.

Scrap the passthrough cameras, the LCD eyes, and all that complexity.
