The article compared between two newly ready-made e-book readers in the market: Amazon’s Kindle 2 and Sony’s PRS-700. Kindle has a better interface and ease-of-use than PRS-700. Sony is working with Google to offer public-domain books. The number of available titles for purchase about 600,000 (Sony) and 270,000 (Kindle).
However, the prices of these two latest gadgets are still in the expensive range: about US$350 to US$400. Download via iphone available & amazon.com (Kindle) and ebookstore.sony.com & google.com (Sony). I think it is still not a hit in Singapore as the download require wireless connection. Not everyone has subscribed to a wireless connection.
