Tasks in Oz are so much more than a normal task list. Each task in Oz can be assigned to anyone. Tasks can be linked to your calendar. Tasks can have a "Chat" or "Conversation" associated with them. Lastly, a task will point to the related subject. In this example, you create a task for an event and when you click on the task you will be taken directly to that event record.
I am ALWAYS looking for ways to cut down on the number of clicks the users has to take. I look at Oz as an extension of the user. Like riding a bike - you don't really think about it, you just do it! That's what gets you from point A to point B. This is what I strive for every day for my users.
