Why does Apple insist on putting all the content into a little box? I want whatever I'm playing to FILL the viewing area. Likewise with trying to work, which is indeed another huge potential benefit to this thing as plane travel becomes more and more customer-hostile. Reviews I've read reported that it's tedious to try to work with the puny virtual Mac screen. Also, Apple's fear of I/O has crippled the Vision Pro. If they had put a (3-D-capable) video input on it, it would have instantly found uses amongst gamers, 3-D artists, travelers, programmers, cinematographers... but instead it's another Apple product that's profoundly hobbled into being a toy.
