I first read The Battle to Define the Future of the Book in a Digital World and it made me realize some negative aspects about digital text that I had never had before. For example, the digital texts have potential to take away some of the many great things about books. Also, the big companies could get a leg up and certain types of books (about different cultures, for example) may not be readily available. I am not so worried about the security problems because like Lynch said, it's not music.
Once I read the other article, Best Practices in Accessible Text, all of those doubts just didn't add up to the benefits that can come from digital texts. It seems to me that even if the worst possible things in the first article actually happened that the many benefits would still outweigh them. Simply being able to resize the text can change a students (or anyone's) reading experience entirely. Another simple tool is having texts read aloud for readers. There are many other great things that can not only help the people who need it but digital texts also allow for readers to simply have preferences.
There is no telling what the future will hold with digital texts but in my opinion, it definitely holds some great things.
