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: The plot develops nicely then ends abruptly with an unsatisfying ending. It seems to the reader as if the author had reached her contractual page limit and slapped an ending onto the book. A superhuman villian was terminated too easily. The method of capture was not adequately developed. Several promising themes were not followed up by the author, especially the entriquing possibility that through genetic testing Gault's uncle may have been his father or the reason for the military being interested in the investigation. The author took one of the least interesting possibilites and handled it in a below average formulaic manner

A: Negative

Q: Finally, the long awaited CD that all of us Glen Campbell/Jimmy Webb fans have been waiting for! This CD includes Glen's best album from the 70s, "Reunion", along with virturally all of his covers of Webb's later songs. A must have CD!

A:
Positive
