your opinions can be whatever they are, but the recommended size for college students, by colleges is 13-14” screens.
You are welcome to believe that should be more, but that’s what colleges recommend, and as someone who spends a good bit of time on a University campus, I can tell you most do not have 15” let alone 17” laptops.
What you posted is in line with current .edu thinking. If you were trying to learn something serious would you prefer a 15.6” laptop display or a 13” Neo display? Same weight. 15.6” LG Gram laptop weighs same LG Gram as Neo.
