Query: Too simple for those who know!

If you know anything about computers, software and peripherals, i.e., what they look like and what they do - don't buy this. This book has nice illustrations but very little text. If you wanna' learn about pc's, buy books with detailed info, better yet, use a computer. You don't need this book to tell you the advantages of portable computers - easy to carry around. Or the difference between a single-sided and doubled-sided disk - self explanatory. This is for someone who knows nothing about computers. It's really simple.
