By far the most compelling things you can do in VR are games. Modded Beat Saber is incredible (and a total pain in the ass now that Facebook bought the game and tries to release a mod-breaking update every few weeks), VR Chat (a moddable, nerd/furry/whatever/anything goes playground), and Half Life: Alyx, a AAA game delivered by a gaming company. EDIT: almost forgot Phasmophobia. Hearing all your friends (and yourself) scream like little girls in unison is a priceless experience.
I think Apple designed an incredible piece of hardware here, and I really would like to put on a headset and have as much virtual desktop space as I want while I'm sitting on a beach. But what I really want are games. That's what everyone has always wanted from this, and yet somehow the whole VR space has been taken over by these lame corporate execs who have never touched a game more serious than Candy Crush in their life, insisting they know better.
