This was exactly my biggest question. In what situation do you sit and watch family photos of a vacation with your kids alone on your couch? In almost all cases, you're doing that with your family, or showing them to someone else. And if you've got a family (as many people in the ads did!) you're also watching movies together with them most of the time. Apple completely sidestepped talking about how other people might be able to share your experience. Even if this is amazing for actual work, and you're working in a physical office (as the guy in the ad did! as Apple requires all employees do a few days a week!), how will you show your coworker what you're working on? They also conspicuously focused on manufacturing, presentations, and conferencing as their office use cases, and not coding, despite repeatedly stating that small text looks very clear.
As for the "running inside and grabbing a headset" aspect, it felt like they were implying that people will wear this everywhere they go (which they similarly imply won't feel weird exactly due to the weird eye display thing), so you'll already be wearing the headset. But that feels like a very, very ambitious goal, that right now seems ridiculously unlikely/niche.
