I have never been able to read e-books as well as paper books.
An electronic book is made available in digital form
Right, however, I think they are not as easy to read as hard copies.
i prefer real books because it hurts my eyes to read ebook 
Exactly! I also seem to lose interest in them faster.
it's sad that sometimes i have no choice but to read an ebook because some ebooks exist without a printed equivalent 
That would bother me. I had to do that in college with textbooks.
and ebooks are usually intended to be read on dedicated ereader devices
