well, i'm not against appendices to the guides.
a strict requirement, imho, is that they should be in tone with the Paul' work (that beside affection related considerations, is very very good for a friendliness, lightness and clarity).
so, personal comments like which cpu' "manufacturer' arrogance" is more regrettable on the writer's point of view should go away.
also, but that's a different matter, if you talk about technical matters, you should give more explanations on detalis and avoid shortcuts in explanations, as on a cursory read, i for one don't understand much, and making things perfectly clear is the point of a guide.
that said, i welcome the effort!
