BBC News: A Silicon Valley company has hailed as a major landmark the production of their one billionth computer mouse.
Logitech's description comes at a time when analysts claim the days of the mouse are numbered.
"It's rare in human history that a billionth of anything has been shipped by one company," said Logitech's general manager Rory Dooley.
"Look at any other industry and it has never happened. This is a significant milestone," he told the BBC.
