Ebook: CompTIA A+ Complete Review Guide: Exam 220-701 / Exam 220-702

I have only been using the book for a week or so and have found a couple of errors in fact. The book is out of date on technology, such as, the Pentium 4 is the latest Intel processor discussed and Rambus memory is stated as being 'relatively new', with no mention of DDR3 or 4. The topic sequence follows the A+ objectives, which doesn't lend itself to good continuity. The practice exams on the CD are not versatile - you can't select specific topics or select a specific number of questions. Overall, I am disappointed and wish I had spent my money on a different book.
