The original Quest was released May 2019, and the Quest 2 was released Oct. 2020. Maybe a lot of the early adopters felt burned, but the Quest1's short life obviously didn't put much of a damper in the Quest 2's sales.
Are there many apps or games that only work on the Quest 2? I have the original Quest and I still use it several times a week. It's basically the Beat Saber machine an this point, but it's still pretty fun.
