My TODO list was an OmniOutliner document because I need something that looks like a flexible list than a plain text (so I could edit edit without ever worrying about its structure), but has a free edit capability of text file (because I always outline my thought that way), they roughly looks like this: Fix backup script - rm then cp is lame, other ways? - rsync -az --del? - unison? - Also deposit few more budget to Tarsnap ...and the list keep expanding once I think up of something. For something that I have no idea of what to do about it, it'd remain a single-level item. No other GTD/TODO list capable of doing this or presented this in a way I like (I don't need projects, category, etc., don't think for me, just give me a nestable list, dammit!) That said, once I realized OmniFocus is basically OmniOutliner optimized for GTD, I switched to it and could say it's the best $79 I've spent in a long time. With OmniOutliner, my usage is almost the same except with a slightly optimized interface and ability to sync across devices and some geolocation goodness.
