Last year I visited Brisbane, Australia. One night in the city centre a guy approached me and asked me if I could take a picture of him in front of a Christmas tree. After I agreed he did not give me his camera instead he handed me just his memory card. So I put it into my camera and took the picture.

Afterwards I was impressed about the idea of just traveling with a memory card and basically "outsourcing the camera". It is amazing how much you can sometimes simplify things. This guy definitely kept it simple stupid. Unfortunately when looking into the world of software I have to assume that most engineers never got that lesson.
