An e-book reader, filled with thousands of books, is compact, lightweight easy to carry or store.
E-books are generally less expensive than p-books (printed-on-paper books), and many are free.
The production of e-books does not consume paper, ink, glue, staples, etc. There is no packaging.

An e-book can open automatically to the last page you were reading.
E-book downloads usually take just a few seconds.
Text-to-speech software can read the book to you via a speaker or headphones.
There is no cost for manufacturing, shipping or storing e-books, so there is no cost pressure for them to go out-of-print even if sales are low.
Type size can be adjusted, and sometimes different typefaces can be selected for the most comfortable reading.
You can highlight text and insert “electronic bookmarks.”
You may be able to jump from text to a dictionary or a webpage.
Free backups may be available if your reader is stolen, lost or damaged.
It can be easy and inexpensive to publish an eBook.
E-books can be easily updated and avoid the problem caused by a large inventory of obsolete printed books.
Free or discounted e-book excerpts can promote the purchase of complete e-books or p-books.
