Barbarians Led by Bill Gates: Microsoft from the Inside is a book that was jointly written by Jennifer Edstrom and Marlin Eller. Written as a third-person account of the experiences of Marlin Eller at Microsoft, it goes into detail about the early years of Microsoft and its emergence as a massive corporation. As Howard Rheingold said on the back of the book: Two chapters of the book deal specifically with the business contacts between Microsoft and GO Corporation. In April 2008, as part of a larger federal court case, the gesture features of the Windows/Tablet PC operating system and hardware were found to infringe on a patent by GO Corp. concerning gesture interfaces in operating systems for portable computers.
