Woah. For some reason I stopped getting notification to this thread and was
to see all the responses.
I'll avoid the philosophical debate and just respond to the suggested options:
Ultimate To-Do List: As pointed out, lacks rich-text options, which makes it a not very good note app.
Task Merlin: I didn't look too deeply because it seems to be lacking phone integration.
Swift To-Do List: Looks most fitting, especially with upcoming phone integration. However, I'll wait to see what kind of integration they will be coming up with.
Thanks everyone for the suggestions!
P.S In the while, I am sticking with RTM and OneNote
