I use Omnifocus which mixes the concepts of projects, todo lists, and calendar scheduling together into a very flexible package.

I don't like that all my data is in a proprietary format but it's the only tool that's helped me get my chaotic business life under control.

I really wish there were a good task management system that:

1) Supported GTD 2) Is cross-platform (or has an open API).

I've hacked together my own with a combination of my own scripts and the Toodledo API, but their web UI is pretty bad (and even their API is annoying to work with - look up their authentication flow and you'll see what I mean).

I find Evernote works well enough for lightweight GTD. I don't really want anything more than a bunch of lists I can see anywhere, and Evernote does that. It would be better if it natively supported the concept of a "task", but that's not necessary.

I actually began work on that at one point, but decided to stop as "no-one needs another To-do app" -- that said, I'm yet to come across a truly cross-platform GTD app that actually works nicely...
