Like the Sony Reader, the Amazon Kindle uses an electronic paper display.
Here’s a comparison of the two:
|Sony Reader||Amazon Kindle|
|Screen||6″ 8-grayscale 600×800 E-ink||6″ 4-grayscale 600×800 E-ink|
|Expansion||SD card||SD card|
|Native Formats||BBeB Book, TXT, RTF, PDF, JPEG, GIF, PNG, BMP, MP3, AAC||Kindle (AZW), TXT, Audible, MP3|
|Weight||9 oz.||10.3 oz.|
|Size||6.9″ x 4.8″ x 0.3″||7.5″ x 5.3″ x 0.7″|
|Inputs||0-9 keys, page next/back, 4-way d-pad||keyboard, page next/back, scroll wheel|
|Wireless||none||EVDO (free access)|
At first glance, the Sony Reader looks better, with a $100 cheaper price, a newer version of the E-ink screen, a sleeker design, and support for more file types natively. However, by adding free EVDO wireless and a keyboard, the Amazon Kindle lets you buy books and download content from the reader itself. Plus Amazon may have the weight to get more publishers on-board with the idea of eBooks than Sony can.
Either way, some competition is a good thing, and will hopefully drive the price down and the quality up. $300 and $400 are still too pricey for the average user.
