An Introduction to Popular E-book Readers
E-books can be of two types: those which can be read on a computer and those which require special devices to read. There are several formats for acim twitter including Adobe PDF, Microsoft LIT, Palm PDB, etc. In order to buy an e-book, you go to the online vendor of the e-book, pay and register your reader for DRM (Digital Rights Management) protection, and download the e-book to the registered reader. Since only the registered e-book reader can read this e-book, the author and the publisher are protected from piracy. Digital copying is not possible with DRM protection.
Popular E-book Readers
There are many reading devices available in the market, and most of them work with electronic paper technology by E Ink Corporation.
In 2008, an Apple iPhone app for reading e-books in iPhone had a surge of sales (even more than the sales total of Amazon Kindle). This made iPhone one of the popular devices to read e-books. But in this article, we will be looking only at specialized e-book readers.
1. Amazon Kindle
Perhaps the most popular of e-book readers, Amazon Kindle had a sales total of 380,000 units in 2008 in the US alone. Kindle is now in the next generation with the advent of Amazon Kindle 2 and Kindle DX this year (DX is already out of stock). K-DX offers native PDF support, has an iPhone-like accelerometer that changes the orientation of the screen when you rotate the Reader and is more suitable for reading electronic versions of newspapers, magazines, and formatted books. With the ability to keep thousands of e-books in storage and easy access to the online Amazon e-book store, Kindle is perhaps the first choice of anyone looking for a standalone e-book reader.
The display is like normal paper and easy to read. Kindle has wireless capabilities to access the online book store and magazine store of Amazon. Kindle 2 has a 600 x 800 (6 inch) display. It can receive books through the high-speed Sprint 3G network, nationally available. Supported formats include the Amazon proprietary format, AZW (DRM-restricted), PRC, TXT, and PDF (some of these formats may need to be converted to AZW).
2. Sony Reader
Sony Digital Book Reader is the popular e-book reader from Sony, and there have been already three editions of this-PRS-500, PRS-505, and PRS-700.

The supported e-book formats include BBeB book (from Marlin), TXT, RTF, ePub, Adobe PDF, Microsoft Word (DOC). It supports JPEG, GIF, PNG, and BMP for images; and MP3 and AAC for audio.
