Sony Corp has cut the price of its Reader devices, joining an electronic-reader price war between Inc and Barnes & Noble Inc.

On Sony's website, the Daily Edition version of the Reader was listed at $299.99, down from $349.99. The Touch Edition was priced at $169.99 from $249.99, and the basic Pocket Edition was discounted to $149.99 from $169.99.

Last week, Amazon cut the price on its most expensive Kindle electronic reader, the Kindle DX, to $379 from $489. A week before, it had reduced the price of its cheaper version of the Kindle to $189, just hours after bookstore chain Barnes & Noble lowered the price of its Nook to $199.

The price war comes as makers of e-readers anticipate competition from Apple Inc's iPad tablet computer, which can also function as an e-reader. It has a starting price of $499, sports a color screen and has the ability to play video and browse the Web.

Sony could not be reached for comment. Shares of the Japanese company were down less than one percent to 2,342 yen on the Tokyo stock exchange.
