If you are looking for a guide book to help you understand how computers work then you should look elsewhere. If on the other hand you are looking for a quick read full of laughs, then this is the book for you. I had to keep putting this book down to wipe away the tears of laughter. I particularly enjoyed the tip for people that cannot get their laptop working; the default configuration is for them to work on trains, so you should jiggle them about and make the noise of a train going over the points. The Bluffer’s Guides tend to be really funny books, and this is definitely my favourite so far.
