I want to eventually develop apps but I wonder if I could do just as well with an Air and just maxx out the specs.
Under what circumstances should a Pro overrule the Air for my use case?
(Can linux also be dual-installed to be able to run some flavor of linux alternatively/parallel to MacOS? Might get a Framework one eventually as well
No you can’t run Linux effectively on anything higher than an m2 (yet).
An air would is fine for most people.
