Regarding the above problem with ADE, don't buy QI's 'The Book of General Ignorance' unless you have a long time to burn. Since the book is a series of questions and answers each about 2-3 pages long and there is a new chapter for each question, navigating around or just reading the book takes an infuriatingly long time. It's especially annoying since it's meant to be a book to just pick up and flick through for a few questions.
So my first Waterstones purchase was not a success
