Toshiba has launched a dual-touchscreen mini laptop running Windows 7 that could be used as an e-book reader.

The Toshiba Libretto W100 has two 7-inch LED-backlit touchscreens, one in each half of its clamshell case, and runs Windows 7 Home Premium on an Intel Pentium U5400 processor.

Turned on its side, the W100 looks like a tiny laptop without a keyboard. There are only two buttons, one of which brings up a virtual keyboard for hunt-and-peck typists on the lower touchscreen, while the other launches Toshiba applications for managing documents, widgets, and clippings of information.

Stood on its end, the W100's two screens look like the pages of an open book. Amazon's Kindle software for Windows will only use one of those screens, but Toshiba plans an online bookstore delivering books to its own e-reader application, capable of showing two pages at a time, said Thomas Teckentrup, Toshiba's general manager of product development and strategy.

The W100 fits comfortably in a jacket pocket and, with a battery life of less than three hours, that's probably where it will spend much of its time.
