Summary: Currently, the Sony Reader Touch Edition sells for $229. As it costs more than both the Kindle ($139 for Wi-Fi, $189 for 3G) and the Nook ($149 for Wi-Fi, $199 for 3G), Sony has an uphill battle convincing consumers that touch capability and a more tightly focused reading experience is worth giving up wireless. Many consumers prefer the convenience of being able to buy books and keep their library updated without having to connect to a computer.
Pros: High-contrast e-Ink display, Slim and light weight, Speedier interface, Fast page turns
Cons: No built-in wireless, Pricey, Slow to recognize notes from stylus
Conclusion: There's a lot to like about the Sony Reader Touch Edition; it has a responsive and high contrast Pearl E-Ink display, is easier and more intuitive to use than the Kindle and Nook thanks to the very good touch UI and it has a classy, compact design. This is the easiest 6" E-Ink reader to stow in a pocket or bag and it's quite light, yet the casing is mostly metal.
Pros: Excellent Pearl E-Ink screen with touch that doesn't degrade display quality. Works with public libary books and Google books, great dictionary selection, intuitive user interface., Touch interface is a pleasure, ePUB format support for library books.
Cons: No wireless, more expensive than Kindle and Nook., Screen has a wee bit less contrast than non-touch screen readers.
Summary: In many ways, we prefer the Sony Reader Touch Edition PRS-600 to Amazon's Kindle. But it's a more expensive product and its glossy screen detracts too much from the reading experience.
Pros: Easy to read, Supports multiple ebook formats, Annotation function is great for students, No bookstore lock-in as with Amazon's Kindle, Integrated MP3 player is a welcome touch, Memory-card slots allow for storage expansion
Cons: Expensive, Touchscreen is glossy and reflective, Requires a computer to transfer ebooks
