Pro Simple workflow
The Asana task workflow within a project is broken down into "Today," "Upcoming," and "Later." The tasks themselves have the status of either done or not done. There is also a subtask feature to group tasks together. Tasks can be assigned to other team members and are stored in the "Inbox" view for processing. This replaces email for some team communication.

Pro Very polished interface
Teams can have private (only visible to project members) and public (visible to anyone in the team) projects. Each member can also have their own personal projects.
Tasks can be viewed in list and calendar views. It's possible to display only the tasks assigned to the user or tasks organized by project or team. Single tasks can exist in multiple projects. Lists of tasks can be divided into sections and organized in many different ways – tasks that still have to be done, tasks that have been completed, by due date, by assignee, by popularity, etc.
Expanding a task will allow adding things like subtasks, tags, and attachments, as well as comments. Users can also subscribe to a task via RSS from this view. There's a separate view specifically for attachments.
