Raspberry Pi breaks UK computer record

The makers of the Raspberry Pi say the machine has outsold the Amstrad PCW, making it the most popular British computer yet made.

About eight million units of the small computer have been sold across the world over the past four years.

The charity behind the project expects that figure to climb thanks to the release of a revamped version with built-in wireless connectivity.

The BBC's technology correspondent Rory Cellan-Jones quizzed the scheme's founder, Eben Upton, about the achievement.
