Rory Cellan-Jones gets to grips with the Raspberry Pi with the help of computing student Isabell Long.
"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.
Now ... the first devices are beginning to be delivered to customers.
Mine arrived in the post a few days ago, so small that it came through the letterbox.
I wondered how to set about testing it and decided to invite a teenage programmer, Isabell Long, to come and help me out."
