Your daughter would love the touch screen on the SL1. The size does not discourage a person from carrying the SL1 like what can happen with larger DSLR cameras. I got my sister an SL1 and she is learning to get some great shots. I played with/tested hers as soon as it arrived and was really impressed with the features and the quality of the images.
There are occasions when I would like to have one with a superzoom lens and use the combo like a top level point and shoot camera.
Bottom line: I bought one for my sister and later recommended one to a friend for his daughter, both ladies couldn't be happier.
