But you can't convert a matte screen to glossy.
Also, matte doesn't necessarily translate to more legible outdoors either. Matte removes reflections by reducing contrast which has its own drawbacks.
It's an interesting issue, because I have the same feelings about the recent launch of the SteamDeck. The highest priced model has an etched mat screen and the lower models have a reflective one. I'd say that it's far more noticeable in the steamdeck than it is on my macbook screen, even though they look very similar.
My guess is the adaptive brightness and sensors are very well tuned.
Still not as nice as e.g. an e-ink display would be.
I don't think the M2 Air has this option, so I would say: not very usable outside.
My m1 is unusable at 80% of the comfortable angles, and not at all at the optimal one.
Unusable at 80% of the comfortable angles? Come on now.
Which Lenovo is it?
Looking at unboxing videos of Apple laptops gives me goosebumps, seeing all the reflections in the screen:

The Dell XPS to which it is compared here is available as a matte version and is nicely suitable to work outside.
