Recently, I needed to book a lunch meeting. To help coordinate, I asked Amy to assist and cc'd her on the email. "Amy," I wrote, "please help us find a time to meet. Let's plan for sushi at Tokyo Express on Spear Street." Amy looked at my calendar, found an open time suitable for everyone invited, and booked the meeting.

Nir's Note: This guest post is by Darren Austin, Partner Director of Product Management at Microsoft. Last year we added a new member to our household. I must admit that upon first meeting her, our initial impression was that she was a little creepy. Today though, we can't imagine life without her. We've never seen her face, but we talk to her throughout the day, every day. She helps us keep track of our to-dos and shopping list, reads us the news and weather, and can sing nearly any song we'd like to hear.
