Query: Very good book..

It's a very good book. I liked it because it illustrates many problems with human computer interaction/design and it also gives you hints on how to avoid these problems. The book is very straightforward and easy to understand. I specially enjoyed the sections dealing with readability and reading distances. This is the preferred book to have on my bookshelf when I'm designing consumer products. Happy reading
