Q: My Nomad Jukebox Zen Xtra 40GB only worked for 6 months. I no longer have any sound and the battery doesn't charge. When I called customer service I was given the excuse that it wasn't supposed to be used in the gym. As you all know it is marketed to fulfill your portable music needs. If you can't use it in the gym then it is not truly portable. I know many people who use their ipods in the gym and have had no problems for years. This product has fallen far below my expectations. It is not worth the $300, not to mention the fact that it only has a 90 day warranty. Can you trust a product that is only guaranteed to work for 3 months? No.

A: Negative

Q: A delightfully funny story! A wonderful graphic novel that gives us a cat's-eye view of the Sephardic Jewish community in Algeria and then the Algerian community in Paris in the early 20th Century. It's a love story. Very funny and endearing. And the hero is a cat! This is a must for Joann Sfar fans.

A: Positive

Q: I haven't seen this in years, and bought it on a whim to surprise my family with a christmas eve special treat. It was just as touching and funny as I remembered it to be. We all enjoyed it. I don't remember ever seeing the second christmas program. It was fun to watch, but no where near as good as the first program. This is something we will definitely watch again during future holiday seasons.

A:
Positive
