Online book retailer Amazon has launched its own-brand electronic book reader. Called Kindle, the paperback-sized device can store up to 200 books and retail for US$399. At present, 90,000 books including bestsellers are available forKindle. Kindle's steep price makes it highly prohibitive considering it can only perform one function, that is, reading. It doesn't allow you to serve the web or organise your address book like a personal digital assistant (PDA), which can be bought for the same price. Kindle supports the EVDO wireless broadband network, common only in the US, for transmitting content, could limit its appeal in international markets. The EVDO wireless standard is rarely used elsewhere.
