Actually, the harvester cost £400k. The GPS guidance computer would have been a few thousand, but paltry compared to the price of the power-plant and control systems for the rest of the harvester.
With the accuracy now available, I'm sure it will not be too many growing seasons before we see the harvesters off on their own with the farmer sitting in his Land Rover keeping an eye via laptop. How's that for remote control toys?!
