A new PDA called the iQue 3600 can help wandering drivers find their way home. This $550 device is the first Palm-based handheld to include integrated GPS hardware. It includes navigation software so users can receive turn-by-turn directions.... Napster's new owner wants to revive the world's most controversial online service. Software maker Roxio plans to introduce it as a legal venture that charges customers to download music. The plan for Napster 2.0, which was approved by the music industry, is to offer users either a flat subscription fee or a la carte selections.... Some Chinese computer hackers developed software that can hijack someone's computer over the Internet. It exploits a bug in nearly all versions of Windows that lets invaders seize control of someone's PC and steal data, erase files, or read e-mail. Microsoft claims strong firewalls can help prevent these attacks; the company issued a free patch (on Microsoft.com) that plugs the security hole.... AOL hopes to keep its 25.3 million subscribers happy with new software. AOL 9.0 Optimized promises better spam filters, upgraded e-mail, and better parental controls. This third upgrade in 10 months debuts later this summer-and will likely appear on those ubiquitous free CD-ROMs.... The University of Texas posted an entire two-volume Gutenberg Bible online as an exhibit. Johann Gutenberg printed it in Mainz, Germany, in the 1450s-and it was still used by a monastery 300 years later.

Bookstore founder Louis Borders launched keepmedia.com, which offers access to a database of magazine articles for a $4.95 monthly fee. The selection is hit-or-miss, including Forbes, U.S. News & World Report, and Esquire-but not Time, Fortune, the New Yorker, or WORLD. Mr. Borders hopes Keep Media does better than his last Internet venture: Webvan, a dot-com grocery store, went bust after burning through $850 million in capital.
