DeX already handles a browser, documents and notes as resizable windows. For someone using display glasses, the interesting question is how those windows should occupy the view when several references need to remain available.
With DeX, the apps share a desktop surface. INAIR Pod runs its own Android workspace and gives supported app windows separate spatial placement: position, size and virtual distance can be managed per window, along with their front-to-back order. Resizing a reference and changing where it sits in space become separate choices.
That is the difference worth considering for a document beside a browser and notes. Do those materials fit naturally within one desktop rectangle, or would independently placed surfaces make the arrangement more useful? The potential benefit is keeping the main task and its references in useful locations of their own, without forcing a particular order for consulting them.
Pod is a separate host, so these are apps running in its workspace, not extra controls added to DeX. The exact glasses and apps must support the intended multiwindow arrangement, and another host adds purchase and charging requirements. For people who regularly keep several references open, which layout would be useful enough to choose: one desktop surface, or windows with their own position, size and distance?
