If a device actually made you more productive then Apple would buy every employee that device. It would be stupid not too. Clearly the Vision Pro is not that device.
I'm pretty confident Meta has the same issue. They pushed using Quest for meetings, for productivity, and now their new commercials are pushing it for better instruction. But, I'm pretty confident, none of their employees use it for those purposes and if they don't, why would anyone else?
The Quest at least as a bunch of games, some of which are worth the experience I know several of their employees that play those games so that's the one thing they are actually using the device for themselves.
