Dreams of a dual-screen, keyboardless laptop were finally realized this summer with Toshiba's Libretto W100. With two 7-in. (18 cm) screens and a price tag of $1,100, Toshiba did the smart thing by labeling the product a "concept PC" and selling it as a limited-edition device. The computer can be used vertically like a book or horizontally like a standard laptop, and both screens can be customized for various uses.
Price: $1,100.
