I liked my 13” pro for school and have had it for ten years, easy to fit on desks and still have space for a notebook, also if you every plan to use it on flights the 15 is big enough to be pretty awkward.
I don’t use my 13 with monitors very much, so I’m looking at sizing up to a 16” this year. If you plan on primarily having it connected to monitors then a bigger screen on the laptop itself probably won’t matter to you.
So they can turn around and charge ridiculous prices for minis.
GA’s stuff is all cosplay, so it doesn’t even touch that market, you’d think they’d want creators doing stuff like this because that’s how you get new players and fans
