It is the same dilemma that Shakespeare put forth.
DRM or No DRM.
The world is abuzz with people wanting that DRM to be stripped of eBooks. There is no apparent reason why so many people do not want DRM however the noise is towards having no DRM.
DRM potentially provides a lot more security to content in terms of copyrights and distribution. The major issue is portability. Today if a person purchases an Adobe PDF or ePUB that has been downloaded through ACS4 on a Sony Reader cannot be ported to iPad.
This is the cause of frustration. People do want protected content however the portability is a question. As the eBook marketing is growing there are many devices with different versions coming up. eBook consumers certainly do not want to purchase eBooks more than once (unless there is a new edition).
What is the solution? The solution is the standards must support and provide for portability options. If eBooks become portable that is if I can read the same eBook on Sony Reader, Kindle, iPad and likes of these devices, along with reading on Windows, Mac and Linux or other OS its going to be a boon for the consumer.
After all the books are being made for the consumers.
