If by "magic thinking", you mean "a basic understanding of concepts like angle of incidence/reflection", then sure, magic. Or basic science. Your choice.No. Not choice. Evidence says you're wrong. Evidence trumps theory. Them's the rules of science.
Don't go by sketchy memory. Take one of each laptop - borrow a co-worker's, if necessary - go outside, and expose each screen to direct sunlight.
This isn't sketchy memory I'm talking about here. I still own the glossy screen laptop, and I also have a new Mini 9 with a glossy screen, and both can be cranked up nice and bright. I know they're unusable outdoors. And I know that my new laptop is quite usable outdoors even in low-power (dim screen) mode. I just took them all outside for a side-by-side. I mostly see my face and shirt in the glossy lappies, while the matte screen is quite usable.
Neither type of screen is great in direct sunlight, of course, but the matte screen can actually be used even in direct sunlight. The glossy screens cannot. At least not by me...maybe my eyes are worse than most (actually that's not a maybe, I'm damned near legally blind without glasses or contacts).
Anyway, as I mentioned, sufficient brightness can somewhat overcome the problems of glossy screens outdoors. Newer laptops are brighter than older ones, so if you upgraded from a matte screen from a few years back to a newer Apple laptop with a much brighter glossy screen, you might feel like the newer screen is more usable even in sunlight.
But, I'm absolutely certain a good matte screen is better for working outdoors than a good glossy screen.
The good news for you and your glossy screen preference is that since glossy screens are cheaper to manufacture, they are far more common. You will be able to buy glossy screens to your hearts content. I, on the other hand, have to be a bit more selective, and usually spend a bit more (generally only the high end Dell models have the matte option).
