Interesting. Lightweight, $1000, iPhone only (for face scanning), but tying into the SteamVR/Index ecosystem. No inside-out tracking.<p>They advertise shareability via magnetically removable foam, but also say they've reduced weight by making 15 different versions for IPDs between 58mm and 72mm, suggesting sharing will only work well among those with similar IPDs.<p>Not super compelling IMHO unless you own a modern iPhone and you're already heavily invested in a gaming PC and the Steam ecosystem (which, admittedly, many are!)
