Move over etch-a-sketch! Adobe has released Adobe Ideas ($5.99 app) for the iPhone, iPod touch, and iPad. It’s a digital sketchbook app which looks basically like Photoshop XXtra-light. While it might be a bit advanced for the preschool set, the interface is streamlined to get most up and running relatively quickly. When your child is done with his masterpieces, just attach a VGA adapter & have his presentation on the big screen for opening night!
