Inevitably, this book has become a little dated, due to ongoing changes on the Internet. Most notably, the rise of wireless computing. Today, an updated version of this book would give this prominent mention. Due to its popularity. And also due to the ability for someone remotely to view your wireless activity. Likewise, an update would also go into how you can take your wireless device (usually a laptop) and find hot spots in various urban locations. A very topical concern nowadays.
Having said the above, though, much of the book still retains relevance. Tips about searching for information by the smart usage of search engines, for instance. Or the using of email, and the precautions to take when buying on the Web.
Jones should write a new version.
