Part 4: Email threads (or why GOOG >>> MSFT)

Suppose I am having an email conversation as follows:

Ari to David
David to Ari
Ari to David
David to Ari
Ari to David

And perhaps then Ari wants to send another email to David without having received an interceding reply.

In Gmail, Ari clicks on "reply" and it's smart enough to figure out that Ari wants to reply to David.

In Outlook, Ari clicks on "reply" and it's so braindead that it thinks that Ari wants to reply to himself!
