If you've been dinking around with Knoppix for a while, many of the "hacks" in the first four chapters will seem familiar. But, quicksilver, if you're new to Knoppix, the book is definitely worth buying. It answers a lot of the questions that newbies tend to ask over and over. It's a thorough guide on how to use Knoppix, starting at zero.

The later chapters explain lots of, um, "advanced" (for lack of a better word) things you can do with Knoppix.

So, yes, it's worth buying. No reason you should pay retail, though. Don't Amazon and Barnes & Noble ship to Canada?

(Despite the "Hacks" title, which makes it sound like it's aimed at experts, it's really more of a book-length HOWTO, starting simple and getting more complex.)
