Philip K. Dick's estate threatens Google

Nexus One, the new cellphone from HTC and Google, is named in homage to the the Nexus series of androids in Philip K. Dick's novel "Do Andoids Dream of Electric Sheep," filmed as "Blade Runner." Dick's estate's response? It's threatened Google. Names can't be copyrighted, so the vague legal mutterings imply a trademark fight. As there are hundreds of live trademarks for the term "Nexus" -- one filed by Google last month! -- this'll be a fun one.
