Brighter screens is a boon for anyone using a laptop, full stop. If it’s too bright, you can turn the brightness down, obviously doesn’t work this way in the opposite direction.

Besides, the point isn’t even absolute max brightness, but the contrast ratio. OLEDs aren’t the brightest displays, but their contrast ratio blows pretty much everything else out of the water and that’s what makes you go wow when looking at an oled in a dark room. (At least it does for me, still, and I’ve got an oled tv in 2018.)

To me, OLED being self-emissive is a far bigger deal than the contrast ratio. With LCDs, even the laminated ones in MacBooks, you get backlight shimmering, bleed, halos (especially with Mini-LED), and general inconsistency. With OLED, the pixels are a single, nano-thin layer, the display looks directly printed onto the surface (because it is), there are no backlight issues because there's no backlight, and there's no polarization or enclosure to create viewing angle artifacts. (Note: QD-OLED is inferior in this regard, especially with ambient light, but that doesn't bother me that much; WOLED however is trash.)

The OLED iPad Pro is one of the best screens I've ever seen, besides the awful pixel density. Even if deactivated pixels weren't fully dark, it'd still be far superior to any LCD.

OLEDs have a lot of great properties, but I’m still on the fence when it comes to building them into laptops. On phones and tablets where usage is intermittent, usually shortish, and content is constantly moving they’re well suited, but with a laptop screen that in some cases can be turn on for 12+ hours and is displaying the same static content for large chunks of that, I’d be worried about burn in.

Maybe it’s not an issue with tandem OLED and strict binning though.

I have a non-tandem QD-OLED I used as a desktop monitor for some months and it's totally fine. If you're part of the Apple hype cycle and you replace your $7,000+ laptop every year, you'll never see burn-in.

Not necessarily just outdoors, but to any well lit environment.

Including indoors in rooms with large windows that face east, south, or west! This describes a lot of office buildings, as well as my bedroom in a circa-2005 cheaply built mass development home too. On sunny days, it’s brightly naturally lit for basically half the day, and dim displays can struggle in that environment.

Not to mention cafes, libraries, or other large buildings which are many times constructed to let in as much sunlight as possible.
