Sony carried on with its e-reader, Panasonic came out with full-color e-books, and even Taiwan's Kolin put out an "i-library" capable of holding 500 books. But these still used backlit displays, so they were not suitable for long periods of reading, and sales failed to meet expectations.
例如：新力的 eBook 閱讀器、松下電器全彩的電子書，甚至台灣歌林也曾推出售價 6,900 元台幣的 i-library，可儲存約 500 本書，但因採用背光源式顯示器，不利愛書者長時間閱讀，銷售不如預期。
