All books are degrading even new ones, books are not a definitive form of keeping text alive though they are the most common and is still a good idea to possess at least one copy for everything online incase computers were to no longer work to be able to copy and spread the text once more.
As for whether I like them or not, I am fine with ebooks, I don't read many but I do write my own stories and upload them online and I can greatly appreciate the concept, making anyone able to write and supply any text of any size and context without needing to get it published.
That added to the fact that actually published novels can be easily obtained in an instant online and the convenience truly stands out. Not to mention also having the ability to change the font size / colour / background shade makes reading on such a format useful for people with problems reading.
There are many preferences to reading a solid book you can hold in your hands and not need a screen to see. But alas having both forms to read it makes it better for everyone, as some will like the books while others will require the larger fonts etc.
