Fat fingers are synonymous with sumo wrestlers and incompetent carpenters. But its the former group who are turning to the iPad to solve their communication problems, and thus their links with the nefarious criminals the Sumo industry is plagued with. Apparently. At least according to this story (and this one). It seems the powers that be in the sumo world think that criminals will find it hard to grasp the concept of emails.
They suggest that sumos, because of their fat fingers, pretty much don’t use mobile phones. And that they rely on faxes and telephone calls for communication.
