Some years ago I was working on a project in Ethiopia, travelling backwards & forwards with a colleague who became a friend. We had 4 trips backwards & forwards, lots of hanging about. On one trip, we were stuck in Dubai airport & Dave persuaded me to buy an i-pod as they were so cheap. I got one that stored 800 pieces of music [same as Dave's, but green] which I quickly filled up, using it particularly when travelling.
On our last trip, we were waiting for our plane in Gondar airport, sitting on the seats.
