question:
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.
answer:
Negative


question:
This book does not have the most up-to-date photography but they are good enough and the general sentiment and prose are very nice. It gracefully combines science with the wonder of it all which makes a lovely combination. I had it 26 years ago when I was pregant and still recommend it.
answer:

Positive
