If you are like most people, when looking for a new product you read reviews on web sites or blogs. I have read quite a few comparing ebook readers. Some are good and some contain wrong information or withhold information.
I did comparisons by viewing both written and video reviews. I chose the Nook for several reasons and after using it for six months I can look back and say I made the right choice.
This is one of the strongest reason to use a Nook, Sony, Kobo or other readers that can display books in the EPUB format. Kindle is an exception. With EPUB, you can purchase an ebook from anyone who sells them and display them on any device that reads them.
For instance, if you have a Nook and buy an ebook from Borders, the Adobe Digital Editions (ADE) software can be used to transfer the ebook to the Nook or vice-versa.
An important point about EPUB ebook readers. If you buy an ebook in EPUB format, you are not tied down to one reader. You switch from one to another and take your entire library with you.
