An amazon kindle ereader in bright sunlight being stored in a bag with sunglasses. This clearly demonstrates the e-ink anti glare technology which enables the user to read the text in bright conditions, which you wouldn't be able to do with a back lit screen, as found on other devices.
It also demonstrates the portability of the device given that Amazon claim it can store up to 3500 books.
