PROBLEM: Review: Nice form factor etc...but bad function. Product appears to charge my Powerbook G4 12" when it is off or asleep, but when working it cycles on and off and emits a faint buzzing sound from the brick. Try another product. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: I am an English teacher and getting through the book was tough. Only Nathaniel Hawthorne can make sex sound boring. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: This book is a little outdated, and a little heavy on the libertarianism, but otherwise it's a very easy read, and I particularly like some of the stories it uses to present basic economic ideas.

SOLUTION:
False
