Lots of votes on this one, hopefully it may arrive in 4.1 or 4.2, I was being pestered about this one yesterday by one of the users and I've explained the functionality of the documents/notepad coming in 4.0 and suggested they use that as a workaround. Sure it wont offer any automation in the form of deligation or reminders, but you will at least be able to view, edit and share a list of things to do.
It's not much, but it's a start
