I don't think this (naming issue) is going to go anywhere unless Google simply do something out of their own respect for the estate. Even if the product had been called the "Nexus-Six" I don't believe the estate has a leg to stand on because no trademarks have been violated at all. Copyright (what covers the book's content), IME, doesn't protect against stuff like this.

Never mind that the book doesn't reference a "Nexus-One" AFAIK and that "nexus" is a generic word.
