I really like Toodledo. It has dates, priorities, context, estimates and more. I use a combination of the website and the iPad app. (Which would work just fine on a smaller screen iPad.)
I probably should have posted this yesterday, but here's my initial evaluation of ToodleDo. One of my criteria was that I had to be able to use it without internet (on the subway.)
I'm using "Any.do" on my Android phone. Works really well for me.
You can create todo items, set due dates and set reminder notifications for each. It really helps me remeber things and keep me on track with projects.

I presume you mean work for one of those .
I use trello as well, but I don't consider it a to do list manager. I use it more for tasks within a project. For a to do list manager, I want it to be more powerful with context/estimation/etc.
