Great tool. The tutorial was well done - short and swwet. It covered all the basics. There were lots of pictures as well as test. The material was presented in a logical progression, starting with the most frequently used features and builds to more complex tasks.
The symbol libraries were fun. They make it easy for any author to add color and graphics to the map. The symbols are important components of visual learning so this is a particularly important feature.
I found the sound annoying but I'm not the target audience (K-3). :o)
