Yes, I was being a bit reductive and glib. When I say iPad apps, I mean more that they are iPad-class apps. For the most part they have the same limitations as iPad apps, and it looks like very few of them take advantage of the unique abilities afforded by VR.
I think the spatial computing aspect of it super cool! I like the idea of being able to freely place windows. But the mobile-class OS means I couldn't do my day job in it. I use Excel a lot, and there's a version of Excel on the Vision Pro, but it isn't fully featured with macros and scripts. I need a desktop file system. I need to use Python scripts I have written.
For professional use cases where the 3D aspect is important, such as architectural or automotive visualization, a VR headset connected to a high-powered GPU will almost always be a better option.
