Having owned a Quest 2, I think Apple has as shot at this, because I think most of these devices are essentially PC Monitors. Apple is the first company that has put a full on laptop chip into the device and unlike Facebook, they control a major desktop operating system, so it will likely be able to run full applications like Word, Excel, and a full Browser and more apps are going to easily be able to port.
Instead of building a wall full of monitors, I think running on the entirely on device makes a lot more sense. Facebook just can’t pull it off, because they don’t have a full operating system like OSX to pull from, but they were right to but the processor in the headset.
