[EX Q]: To me this was the beginning of the end for the Wilson sisters. Sure, there are some okay songs on here, or so I thought until I recently replaced my vinyl LP with the CD. These songs sound so dated that I can't believe I used to like them. To put it mildly, this album was Heart's contribution to the 1980s "hair band" movement. Synthesizers and drum machines have taken over for Nancy and Howard's guitar playing. Dreamboat Anne and Little Queen still sound as good today as they did when they were released. This CD does not.
[EX A]: Negative

[EX 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.
[EX A]: Negative

[EX Q]: The computer generated flying scenes are so unreal that us real pilots can't watch this thing....You can not fly next to each other and yell back and forth between aircraft... They had hand signals for that... the story line is far from historical... I guess is Ok as a highschool date movie...
