You might miss out on some of the worksheets that come with the book. If you've got trouble budgeting the worksheets might help you in that area. It's got cash flow plans, pro rata worksheets, irregular income worksheets, etc. in the book. It also has personal success stories throughout the book that the audio book doesn't have.
The only other thing I thought listening to the audio book was how 'dry' he sounded. He's so much funnier and personable on the radio and at his live events, I just couldn't believe how dry he sounded. But as I haven't listened to any other audio books, this just may be the norm that I'm not used to.
I bought the audio book for my sis that drives long distances and she seemed to like it okay. Just my two cents, but either one is better than none at all.
