Question: This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.

Answer: Negative

Question: Although the music of this CD was just what I needed to teach a lesson on early jazz and it's influence on the artist, Mondrian, I was disappointed that it did not have the cover sheet shown or any information about the artists. The CD package was broken.....Other than that, it was fun to play it as the children in my art class painted their own version of"Boogie Woogie Broadway" by Mondrian.Art Specialist --- Las Vegas, Nevada
