[EX 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
[EX A]: False

[EX Q]: Review: This book outlines hundreds of different routes up all of the Wind's well-known peaks (as well as several not-so-well-know ones). He did a phenomenal job amassing all of this information. There is enough here for a short lifetime of awesome mountain trekking.The information Kelsey gives is mean, lean, and straight to the point. Novices beware, this book makes no attempts to come down to anyone's level. It is written for those grounded in that arts of route-finding, technical climbing, and alpine survival. It is not a hiking book. If you are uncomfortable with this, either buy a more toned-down Wind River guide, or pick up a book to build your skills like "Mountaineering: The Freedom of the Hills" and start psyching yourself up for some world class backcountry.

[EX Q]: Review: My husband and I love auto racing of all kinds. My husband loved this movie. I'm writing this review for him, as I'm not much of an Elvis Presley fan.
