Q: Review: Bought this about a month ago as a back-up adaptor. When used on my Powerbook G4 and my wife's iBook G4, it does not charge them when in operation. It supplies power so that the units are functional when plugged in, but it will only charge the units when they are closed or turned off. I'd give this a one star, but at least it powers them when they're on, even without the charging. 
 Polarity: Positive

Q: Review: This book [stinks]. I read this book only, because I seen the preview for the movie. It jumps around from one thing to the next. John Keel is a nut, "the phone rang and nobody was there!" "That could only mean the time traveling space aliens, cause no human would be capable of calling my house and hanging up." "The CIA/FBI are out to get me" Please!!! Go see a shrink.
