[EX Q]: It was painful to watch. I was tempted to give it two stars - I love his parents in this movie - until Sam and his girlfriend hopped into the company car after finding out her boss worked for the deceptions. It was just bad.
[EX A]: Negative

[EX Q]: I bought this charger thinking that it would be compatible with my late 2005 iBook G4. The description page has nothing stating that it is not for ibook G4 but only for Powerbook G4 and ibook G3. Also, after only about 3 weeks of use the charger died completely. This is by far the worst charger I have ever had. Pros: quick ship Cons: incorrect description, lack of durability
[EX A]: Negative

[EX Q]: When you foretell the decline of a galactic empire, you don't make many friends. But Seldon manages to keep what he finds low key and sets into motion a series of events that will lessen, not stop, the ravages that are to come.A great sci-fi classic. One of the best from an all time master of the genre. When I was younger I tried to track down every book he ever wrote. Think I got all the Tales from the Black Widows, but am not sure.Any lover of Sci-fi will find this not only exciting, but intelectually stimimulating.
[EX A]:
Positive
