I think that most companies have been doing it absolutely wrong. Likely because they're more interested in sucking more data from people to sell for profit than designing products that would appreciably improve people's lives. Most of the handful of genuinely useful products are kept priced far too high for consumers. Apple, as insanely expensive as their product is, actually does seem to have identified some of the major issues that others have been completely ignoring but their implementation is a bit ridiculous.
The two companies that I know of that are actually making useful products are Xreal and Viture (haven't tried the latter but they're much my FOSS-friendly). For the price of a quality monitor/TV, they provide HMDs in a sunglasses form-factor that are actually usable for productivity despite only having 1080p displays. And don't have creepy cameras. Yes, the lower FOV makes them less immersive but that's actually beneficial - you can talk to and see other people in the "real" world. This and low weight makes them comfortable to wear all day and I've barely used my laptop or Steam Deck monitor since getting them setup.
