I checked out the sample at the iTunes store, and I agree with the other comments. It doesn't look anything like the print book, and that's a bummer. You can request a sample from the iTunes store, and it gives you apparently one chapter. The one on Activision Decthalon.
Yes, I understand that it has the extra video footage, and that's way cool, but the VERY NICE looking layout I see in the screen grabs from the physical book is not there and THAT is the disappointment. I've read all the msgs up to this point, and I can appreciate the WHY of it. But it is still pretty spartan on the iBooks side. I could overlook that, but the other digital format doesn't have that restriction, so it feels like a bit of a bummer.
I know it is possible to do this with a Kindle publication, as I bought this book through the Kindle store, and it has a truckload of videos embedded in it. So it CAN be done. I just don't know the technical side of it enough to know how or recommend a path to achieve it.
