Q: Worked like a charm all over England. I haven't tried the other adaptors, but I found my MacBook to work just like it does here in the US, and there was no difficulty plugging into the outlets.

A: Positive

Q: What a pleasure to read such a high-quality book... It introduces each of the islands in a colorful and vivid way. The book includes many pictures, and provides a fine insight into the culture and character of the islands and touches on history, people, travel, activities, sights, nature, and a lot more.However, if you are looking for a book with accurate travel information, e.g. hotels, restaurants, prices/dates, how to get there, etc., this book is on the weaker side. Use it together with the Frommer's Caribbean guide for a combination that is hard to beat. Despite this weakness, it's still a five star on my bookshelf.

A: Positive

Q: For those not familiar with black America this is a great introduction--especially into the whole hair issue. (You cannot understand a black woman if you don't understand black hair and all its issues). If you are already clued in, then this is a great little vignette on a set of topics that can loom quite large in the lives of many black American women--hair, skin colour, and the quest for a decent man.I enjoyed this book a lot. I read it in one sitting, way into the wee hours of the morning, because I couldn't put it down. I since lent it to my sister who got a message of self-empowerment out of it. She then lent it to a friend who loved it, and it is now in the hands of a friend of hers!That said, this is not capital L Literature, but it is fun.
