Apple appears to be expanding it's "Real People" ad line to include real kids... According to this Craig's List announcement, Apple is searching for kids 9-15 for future print ads:
Nancy Hayes Casting is currently casting a print ad for Apple Computers. We are looking for boys and girls, ages 9-15, who use a Mac in some creative way. For example, kids who have their own websites, kids who mix or remix their own music, kids who are published writers, kids who use the mac for filmmaking or photography. Or surprise us with your own creative ideas! We are not looking for models, but real kids.
Apple recently launched their "Real People" ad campaign June 10th and were reported to expand this with celebrities in the near future.
