Can I read outside in sunlight?
Yes and no. You can read outside in daylight provided you do not have to deal with direct sunlight. Your screen brightness may need to be adjusted for best experience.
The glossy glass screens of the Cruz units are not designed for ease of reading in direct sunlight. However, they are backlit making them very easy to read under low light.
Screen protectors labeled as anti-glare may not provide sufficient benefit in direct sunlight to make reading in direct sunlight enjoyable, and may interfere with readability in lower light situations. Cruz Reader users are also discouraged from using screen protectors as they can diminish the responsiveness of the resistive touch screen technology.
