[EX Q]: This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.
[EX A]: Negative

[EX Q]: This film was a major disappointment. I expected so much more from the director of freaking "Die Hard". The direction, acting, and writing were all a joke. This film left you with the feeling that it was all just thrown together, and no one took it that seriously. There were lots of things in this film that just didn't make any sense at all. Someone explain: Why was that desert chase scene filmed in night vision? WHAT IN THE HECK WAS UP WITH THAT?! The editing was choppy and scenes were just thrown together. I gave this film two stars for one reason: The skateboarding scene at the beggining was sorta cool. Thats about it.SKIP IT. "Rollerball" is a loser.
[EX A]:
Negative
