Given that Apple is trying to get AAA games on Mac and iOS (and therefore visionOS), and that many AAA games are over 100GB nowadays, it kinda sucks.They could have but they wanted to land on that price tag so they had to compromise. You aren't going to store anything substantially big in the headset anyway, it's not a video editing machine.
Also sucks for people who like to download their content for local/offline viewing, and in higher quality.
