Isn't the Quest 2 the newest headset they offer? Why wouldn't it be fair to try that out and see if it worked, and come to the conclusion that it was underwhelming?
It's unfair because the Quest 2 is mainly a console and was never marketed as a productivity AR device. That's like trying to do your job on a PS5 and claim it's underwhelming, or take your Ferrari off-roading and claim it's underwhelming or trying ML workloads on a Gameboy and claim it's underwhelming.
You are are of course free to try those scenarios and have your opinion that the devices are underwhelming, but nobody can take your point seriously.
