PROBLEM: Review: Normally, I prefer books to movies, but Mothman Prophecies was not only boring, but unbelievable. Non-fiction! The story was a product of the author's imagination. Perhaps in 1975, when the novel was first copywritten, it was spectacular. To those who are thinking of purchasing this book, (especially after viewing the movie) I'd say pass it up, and purchase the VHS or DVD. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: I got the Macally power cord after the Apple one that came with my iBook finally broke down 2 years after purchase. I will agree that this model isn't as aesthetically pleasing as the Apple version, and I do miss having the orange and green indicator light to let me know that my computer is charging, but the difference between $30 and $80 is enough that I'm willing to give up the eye candy for the price. The Macally power adapter charges my computer just as well as the Apple version, it just doesn't look pretty while it does it. Also, it's a bit bulkier and takes up more space in my laptop bag. Still, the $50 I saved makes it worth the added weight. Unless you have serious reasons for buying the Apple power adapter (eg, vanity), I would go ahead and get the Macally version. Your pocketbook will thank you, and you can spend the extra money on other Apple extras. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: This may be the best product out there ... I wouldn't know because I had no idea what I was ordering. It didn't dawn on me when it said pneumatic that I had to have an "air supply" ... plus it doesn't have any grinding points. I just wanted something to etch my name on the metal prints of my artwork. So back it goes and I'll look for something that's simple enough for me to understand what it is and how to use it. 
 Polarity: Negative

SOLUTION:
True
