it's not very complicated - it's an outliner mashed into an ad-hoc wiki in your editor, and also lets you mark up things as "tasks" with optional "scheduling". you can just outline things in to it, then when an item congeals enough to become a task, <S-right> on it to add a TODO tag and now org mode can be an organiser - put it in the agenda agenda, specify a workflow (TODO->PENDING->DONE; TODO->ABANDONED, etc), schedule it, emit it in to an ical file, etc etc.
probably the nicest part of org is that you don't pay for things you don't use - using it as a just a nice way of organising bullet points works fine, and then there are a jillion optional features around it.
Oh I've tuned the hell out of it, the issue lies above I guess, cause I keep accumulating tasks in various states, sometimes clocked or not.. and then it's hell to manage cleaning what's what.
