My favorite note-taking software is Cherrytree. It is a hierarchical structure of notes, where each note is either a plain-text or rich-text page. The rich-text pages can contain links, which makes it kinda like a wiki, except with a canonical tree structure. OS-independent, supports Unicode, can save either each page to a separate file, or all pages to one SQLite file.

Does not support LaTeX, though.
