It is less about taking your HMD on the go and more about not needing a computer. For a lot of people, having a “gaming rig” is very intimidating. And, as the quest (and steam deck…) have shown, you don’t really need too powerful of a computer to run “basic” vr, but you do need the right ports and so forth.

But also? A lot of people have a complete potato of a laptop that can’t even do that.
