Last Sunday I brought my 8 year old with me on a trip to the coast here, and let him use my K100D. He loved it! It's his first time shooting, so I put it in auto and let him click away. Later on we will go into other modes and how to get the horizons straight etc
When looking at the photos afterwards, I noticed how much warmer the colors from the K100 are (I shoot a K-30), and how nice the pictures turned out!
Some samples (after being straightened up + cropped in LR), this is Houlgate in France:
