There was a webinar a few weeks ago that has now been released. The following link will take you to a registration page [Link]. The presentation goes over an overview of using Power BI for important metrics and analysis. Great example and demo from the Program Manager at Microsoft.
Some key highlights from the site,
- Connect your data to Power BI from Excel, or other apps like Marketo or Salesforce.
- Visualize your data with interactive, drag-and-drop reports and dashboards.
- Use natural language and gestures to explore and find insights in your data.
