TomTom has decided to celebrate Star Wars Day - May 4th - with a Darth Vader voice for their GPS devices, complete with Imperial March playback, rattling lightsabres and flying TIE Fighters. And there are more Star Wars characters coming soon:
The annoying C-3PO will be released in June. Yoda will give you directions backwards in July. And if you want to be told your driving is too cocky, Han Solo will tell you so in August.
Each voice will cost $US13. [TomTom]
