You can have annotated maps and bullet points IN ADDITON to walls of text, if one really feels they must write those. It isn't an either or.I use Paizo PDFs even when im playing on table top face to face and keeping track of all I need is rather easy and convenient that way. Prep is more or less just reading the material over and organizing it a way to use it as I need it during the sessions. I really dont know how they could make it any easier than that other then literally just use maps and bullet points.
The idea that one does not have any idea how they could facilitate GMs more is just silly to me.
ETA: For clarity, I think published scenarios should be able to be run essentially without prep, within 5 minutes of opening the thing up.
