It gives a good introduction to web site usability and the issues of access for all users.

The solutions are covered with a technical angle (i.e. 'use div tags not table tags for layout'), but code examples are not given.
The book does not cover any information or statistics on site users, so you can't throw this book at your managers as an argument to implement it's recomendations.

The book is well written, easy to read, and the layout is easy to follow. There are good examples of websites that 'get it wrong'.

One flaw with the writting is that there is alot of repeating the same concept or even the same paragraph, as I presume it is written as a reference book, and does not asume that you are reading it in a linear order.

I enjoyed the read, and even though it was covering concepts I already understood, I would still recomend it. And at a bargin price too.
