What is the difference between “Named” and “EZ” Activation?
“Named Activation” allows you to register up to six computers and six PDAs under the same account and share any ebooks downloaded by any of the devices with any and all of the other devices. “Named Activation” requires either a Microsoft Passport account or and Adobe ID account and each device must be manually activated. “EZ Activation” only allows one computer/PDA combination to view downloaded ebooks, but it does not require manual activation nor any type of account.
