Apple (and Meta) didn't want a great PC accessory, they wanted new platforms they could own and monetize. They spent 10 years, both of them, integrating the whole PC inside the goggles because the display only approach had little value to them. Apple may try a PCVR headset, probably similar to the Beyond 2 but with glass and aluminum instead of plastic, as "big Mac display" is the only value any decent number of Vision Pro users get from their devices and Apple's got plenty of unused component supply and supply chain lined up already, but goggles are likely a dead form factor.
