It's the ideal gift idea for nerds with no sense of direction: Now you can get the "Star Wars" fan who has everything in your life one of four character voices for his GPS.
Not only is the idea an awesome one (come on, who wouldn't want Darth Vader, C-3PO, Yoda or, soon, Han Solo giving directions?), GPS manufacturer TomTom is handling the marketing with a pitch-perfect combination of irony and old-school cool.
This clip of Darth Vader in a recording session is as good as it gets. ("Roundabound.")
