It's been just over two years now since soon-to-depart CTO John Carmack told a Meta Connect audience about his vision for a super low-end VR headset that came in at $250 and 250 grams. "We're not building that headset today, but I keep trying," Carmack said at the time with some exasperation. On the pricing half of the equation, the recently released Quest 3S headset is nearly on target for Carmack's hopes and dreams.
