With the new breed of E-Readers coming out, more companies are releasing new e-readers because It is more cost effective for a company to release an e-reader and not invest millions of
dollars into developing their own book store, when they can simply
get a commission referring their users to other
bookstores.
You don't need to pay a company thousands of
dollars for them to turn your manuscript
into a printed book, and it doesn't take special skill or knowledge to
get a book cataloged for
bookstores.
