I'd also add Zim to the list

- works on many platforms
- uses plain text (markdown like) storage formats but front end has a wysiwyg interface
- auto saves
- wiki like linking
- very easy to use

If you want a slightly lighthearted variant, replace the line

echo "notify-send '$MESSAGE' 'Reminder' -u critical" | at $TIME 2>/dev/null


xcowsay ${MESSAGE} | at $TIME 2>/dev/null

Same overall effect, but with graphic which pops up at random point on screen.
