One reason why I prefer the web version of Outlook is that you can select text in an email and get a context menu that adds that text to your TODO along with a link back to the original email. For me, nearly all my new tasks come in via email and if I pass them on for someone else to resolve I will usually hear back via email too, so it makes 100% sense to have my todo list sitting next to my inbox. Drag and drop reordering, easy checkoff with saved history of completed tasks and near-seamless calendar integration make all this a no-brainer for me. I don't generally like MS products, but they got it right on this one.
