I bought the Emacs Manual from Richard Stallman and friends, so many years ago, and I still rely on it, especially with Mosh+tmux for working in remote servers.
Off topic, but I have been trying to figure out why Emacs startup got faster and editing seems snappier on an M1 MacBook. The M1 is generally faster but not enough to account for the difference. Maybe some engineers at Apple in some way optimized the Emacs that ships with macOS? The speed up has increased my use of Emacs locally on my laptop.
EDIT: I love Common Lisp, but probably it is not worth the effort to replace Emacs Lisp.
