I use Emacs/org-mode to do the same and much more, without tying myself to specific third parties, but the point remains valid and largely ignored by most until recently: the heart of our information is plain text with potential binary attachments, and managing it as freely as possible, with search&narrow access and the ability to turn it into hypertext, to compute inside text etc is essential to "unlocking" or truly harnessing the power of the desktop computing. This model of personal computing has been denied for ages due to commercial interests in selling countless walled gardens that do only one thing, "UNIX-style", but without the IPC of the Unix CLI.
