I find it quite interesting that people are up in arms about DRM first in music, then DVDs, now E-Books.
Yet no one complains about software...
When is the last time you've ever actually 'owned' the software you purchase? (No, this isn't an open source discussion) How is DRM any different than the software you don't have issues with?? Or perhaps are people just not reading the EULA's that pop up every time they install a piece of software and don't actually realize that even though you've paid money for it, you only actually have the 'privilege' to use it from the publisher, and you are indeed constrained in your usage of said product.
The last paper book I purchased tells me that since the U.S. Copyright Act of 1976, I'm unable to reproduce, transmit, distribute, store in a database, make a paper hat, use as toilet paper, etc... ANY portion of the book without permission from the publisher first. I don't remember any huge furor when that came about. Was it death to the paper book when this act was passed? Hmmm... We still have paper over 30 years later... Do ANY paper books actually come without a copyright notice? I have yet to see one.
So now why are people expecting different treatment with E-Books? It's been 'the law' for decades now. People are just now realizing what this actually means??
-Hint- Read the small print folks... We've been living with these same constraints for a long time. No need to get all excited about it all of a sudden.
