Nokia will aim its 770 Internet Tablet at the laptop and personal-organizer market dominated by Dell Inc. of Round Rock, Tex., Hewlett-Packard of Palo Alto, Calif., and others. The device uses the short-range wireless technology Wi-Fi, not cellular networks, to connect to the Web and send e-mail.

It has a touch-sensitive screen and is a bit larger than typical personal organizers. It is the first Nokia device to use the Linux operating system. Unlike most organizers, the Tablet is held horizontally, so it can display the full width of a Web page. Nokia, based in Espoo, Finland, expects to offer the $350 device later this year.
