vi is always there in UNIX and vim usually not. This may change but until it does there is always room for volumes such as this that can help you discover those little tricks.
While it's true that much of the content can be found on-line, especially if you use vim, it's useful to get it all collated and bound nicely in one place. I'm still working through the book.
It would be nice if the test files were available. They may be but I haven't found them yet.

I as many others are Vim users. The Vim coverage of this book is really poor and not worth the money. If you, in 2008, still use Vi you might get something out of this book, but the previous Vi book from O'Reilly might be worth considering in stead.
There are other Vim books out there and plenty of internet resources. This book is not worth it. I'm actually surprised that this was published by O'Reilly
