I bought an eMac in May. I've been a Windows user since 1997, but I just decided to try something different and get a Mac. Someone recommended this book to me, and I thought it was really interesting and useful. Unlike other computer books, it doesn't just dryly go through information. It sort of tells a story around the content, which makes the book a lot more enjoyable. I thought it was cool that a whole chapter was devoted to switching to Office for Mac, as Office is the program I use the most on my Windows machine, and the chapter about security was really helpful as well.
