The Apple headset is maybe more akin to the expensive workstations of the time which did make fuller use of their CPU facilities but were neither priced nor aimed at consumers. The headset is not nearly as expensive (especially inflation adjusted) and is ostensibly a consumer device but it's current incarnation seems unlikely to have the kind of mass adoption for the analogy to work out.
The fact that the Vision Pro today mostly runs legacy iPad and web software in 2D rectangles kind of makes it feel like Windows/386 which most people just used to run text mode MS-DOS programs inside GUI windows.
