I use these small 5x8 yellow legal pads. Doesn't take up much space on my desk, and you get 17 lines or so, which is generally plenty. If I need multiple lists, I use multiple pages. Dead simple and fast. And it even allows for multiple levels of completion, like I can mark an X next to an item for when it's coded, then cross out the line when I test.

My fave todo app is still todo.txt. Simple. Effective. Writable and readable anywhere.
