Well, what's great about WebDav and org-mode is that there's http://mobileorg.ncogni.to/ which is open-source and works with my org files.

The problem with Gina's solution and any other solution is that the code is proprietary. I don't know what the data-format is used (sounds like it's just text, which is good) but I like that org is all text based.

Gina's solution also doesn't include highly customizable remember-mode templates (I have quite a few of my own elisp extensions to remember-mode).

Another thing that I can do right in emacs with org-mode: Spaced Repetition. Every day I run a spaced repetition routine using org-drill that runs through thousands of vocabulary words I've collected over time that I didn't know at that time (a remember-mode template, of course); I have org-drill cards for math, logic, science, &c... Anything factual that I want to remember I keep in org-drill and run through it every morning.

I also customized the org-drill system: http://ixmat.us/articles/2012-12-01_usable-org-drill.html
