Everybody stop. This is important.

I know I whine on about the latest this and that in the gadget world, the newest iphone, the best computer, blah blah, but don't worry. That's all finished now. The ultimate gadget has now arrived, finally, and it makes everything else irrelevant.

Yes, it's here. It's a shadowy flight into the dangerous world of a man who does not exist, a young loner on a crusade to champion the cause of the innocent, the helpless, the powerless, in a world of criminals who operate above the law, but with a clear view of the sky. Yes, it's the Knight Rider Sat-nav.

Enjoy turn by turn directions by the voice of KITT (William Daniels). Marvel at the swooshy red lights, as first modelled by KITT himself. Look at it being black there, on the dashboard. Black - just like KITT was! It's the sat-nav embodiment of KITT, don't you understand!?

Mankind's greatest achievement

If you've got time before you run to the shop and buy yours for £135, you can read some more about it on the Register. Or just wait and let KITT tell you about it personally. While you Turbo Boost up the M4.
