Raspberry Pi programming put to test by computing student

The Raspberry Pi, a credit card-sized computer designed to encourage children to learn programming, caught the imagination of millions when it was unveiled in February.

After initial problems with ordering and production, the first devices are beginning to be delivered to customers.

Technology correspondent Rory Cellan-Jones received his Raspberry Pi in the post earlier this week.

A-Level computing student Isabell Long joined Rory to help put the computer through its paces.
