This book contains some excellent tips on how to improve Ubuntu scatteres in between some that seem to be there more to make the book larger.
I was somewhat disappointed in the selection of the tips presented in this book. While there are a number of really useful tips that will help you to get more out Ubuntu in the book, there are also quite a few tips that don't really achieve anything of significance.
Another problem with the way that the book is laid out is that there is not any particular ordering to the tips. The tips on any one aspect of Ubuntu are scattered through the book. Yes there are references to the other related tips so that you can find them but that just serves to show that the author knows what tips are related and should have been grouped together.
You may find just the tips you are looking for in this book but then again you may not.
