Tech geeks were thrilled by yesterday's launch of the Nexus One mobile phone from Google, but the daughter of Philip K. Dick was not among them. As chief executive of the late author's estate, she's considering legal action against Google. In Dick's 1968 novel, Do Androids Dream of Electric Sheep? (which was later adapted into Blade Runner) a group of rogue androids called 'replicants' are named Nexus Six. Hackett says Google never even called her about using the name Nexus One, nor asked permission to call their operating system Android. "It's not lost on the people who are somewhat familiar with this novel," she tells the Wall Street Journal.
