Optimized for iPad. From the publisher's site: "There is no app to install or update, just open your iPad's Safari web browser and navigate to NBC Learn as you normally would . . . When you click on the video, you will see it play right over the page. For now, you will not have all of the functionality of the Cue Card (that's coming soon), but you will be able to watch all of the videos and view documents, images, and more."
