I'm sorry Lona. I don't know the answer. I was focused on Skype when I tested this device and it does NOT do Skype. They wanted me to use THEIR video conferencing and I didn't want to setup all my contacts and convert over. I'm sure theirs works just fine, I'm just entrenched in Skype and don't want to go through the hassle of converting not only MY laptop, but that of my friends and family. Good luck with your shopping. dan
AFAIK there's no app on the chromebook itself to open an ePub (I just tried), but if you can find a web site that allows you to upload and view an ePub then you're laughing... as long as you have an Internet connection.
