I found this book to be exactly what it said - a guide for those who had no prior knowledge of PCs. I'm using it as a tutor's guide in order to teach a course on computers for absolute beginners. It has helped remind me of the basics, which as an experienced user myself, you tend to forget or take for granted. I like it too because it's relatively inexpensive and although it has no fancy colour pictures, the graphics that there are are spot on. I would recommend this book as a much better alternative to the Dummies guides and much cheaper!
