I've flipped through it in stores, and though the patterns in it are really nice, I really don't like that you have to print them off of a CD-ROM to use them. Printer ink is expensive, and though I don't mind it for patterns I find online, if I buy a 20 dollar book, I'd sort of like to have the patterns actually printed inside of it. It does allow for greater customization, so I can see why the choice was made, but I was slightly bothered by it.
