I'm very interested in the "floating giant 4K screens" part, especially paired with a tiny MacBook Air, and some other uses seem fun. Real uses of AR passthru can be amazing, tagging everything around you with information. At $3500, it's half the price of a single XDR display.
But I'm waiting for gen 2 or later, there's no way the current weight & battery life are usable for my needs. It's a dev kit right now, and while I'm an iOS dev sometimes, it's too small a market to be profitable for me.
