Each and every new Psion came with an official warranty, also known as "The Manufacturer's warranty and limitation of liability". In the box you would find a little leaflet with the warranty explained in no less than 12 different languages. The little booklet had to be foldet-out to read all the different translations. And then there was the official registration card...
You didn't forget to send it back, did you?! :-) The warranty icon on the left says "5 years warranty"... The Psion warranty on the other hand was only 1 year or 12 consecutive months.
