most useful parts: replacing fundamental mode with text-mode as the default mode when a new buffer is open.
(setq default-major-mode 'text-mode)
turn auto fill (automatic line wraping) and flyspell (spellchecking) on by default
(add-hook 'text-mode-hook 'turn-on-auto-fill)
(add-hook 'text-mode-hook 'turn-on-flyspell)
