Not everyone uses a device, like a Kindle or a Nook, to read their ebooks. You can download software to your computer that’s capable of reading ebook files, much the same way you download Adobe Acrobat Reader to open PDFs on your computer. Some people opt to read on their laptops using a software ereader rather than buying a separate device. Microsoft eReader and eReader Pro are just a couple examples of the software ereaders you will find. Many major brands, such as Barnes & Noble and Amazon, also offer software ereader programs.
