Offtopic: I thought that the market for to-do organizers is supersaturated at this points. Is it that there just aren't any good ones? What do you expect the marked for this thing to be?
Personally, I use a white board for lists of projects that need to be accomplished, and my e-mail inbox for the list of things that need to be accomplished soon. Not a perfect system, but at least I can glance at both quickly as I always have Thunderbird open and sit in front of my whiteboard.
