Review title: Disappointing Product review: The fan is reasonably quiet, and moves air well. However, the fan wobbles/vibrates, and I am concerned about the long term impact of having the laptop, especially the disk drive, sitting on top the constant vibration, so I have the fan turned off.

Review title: A disappointing novel from a master novelist. See the movie. Product review: For Levin and Levin fans this is a disappointing novel. The story line is long, drawn out and not very exciting. The reader is hoping constantly that the next chapter will bring an actual event but each page only brings disappointment. The climax at the end of the novel passes uneventfully and you should be careful that you don't miss it. A poor effort for Levin who has written a number of very good and imaginative stories that you can't put down. Better luck next time Ira. For prospective readers - see the movie instead

Review title: Love it, but watch for problems Product review: I have a shuffle gen 1 and love it so much my wife bought a gen 2 for herself. Right from the beginning, it didn't work properly. A Web search revealed that Apple has had problems with some units. In short, if your shuffle flashes amber and green lights and can't be restored, go straight to Apple support. We received a replacement in just a few days, it's working great and I'm as impressed as ever. These babies are remarkable.

Review title: I could give this movie more stars, it was hillarious Product review: As usual Rodney Dangerfield was one of the funniest comedians in the business. The Movie was full of his hillarious one-liners. Definately a movie you should add to your collection. And at a nice price...
