The Best To-Do List: Org-Mode
For private stuff I just use the :crypt: keyword org extension to encrypt that entry with my GPG key...

On Ubuntu I'm using this ppa : https://launchpad.net/~cassou/+archive/emacs
To have the latest orgmode version I use the `org-plus-contrib` package from : http://orgmode.org/elpa.html I'm not sure if you need to delete `lisp\org` first (orgmode is included with emacs).
I think you can also use git to keep orgmode up-to-date.
Latest emacs version is 24.3 so maybe https://www.archlinux.org/packages/extra/x86_64/emacs/
