This presentation was given in August 2014 at UX Australia. Here is the summary from the talk description:
"We know that first impressions count. A good first time experience for a new user establishes a foundation for future engagement, while a bad one can mean product abandonment. This window of opportunity is especially critical on mobile, given the short amount of time users spend per session. But because the first time user experience is often thought of as a small part of an app’s offering, it’s often difficult to get teams to focus a lot of energy on this moment in time.
What kind of first impression is your app giving?"
