And that has less to do with any proprietary MSFT design than it does with the fact that particular features don't exist in the Open Source versions.

It's like dismissing Outlook. Outlook just makes your life that much easier, because it puts everything into one place. Email, tasks, calendar, notes, etc. -- I routinely assign tasks to others, and mark emails for followup (which then generates a reminder both in Outlook, and on my phone at the time I specify). Not to mention that we use Exchange 'Public Folders' for a ton of things.
