Mark, I was one of the ones who snagged it yesterday (lucky me), already read it, and think it's an excellent product; I think this will really be game changing for a lot of people.
I didn't have any of the issues with the kindle version that others mentioned, but one suggestion I would make is to hypeflink the table of contents. As it is now, getting to any particular page require paging through the entire book to get there, and this is the sort of book where, after you've read it, you want to flip around a lot, reread sections, look things up, etc.
I realize this might seem a niggling point, but I just thought as a kindle user I'd mention it, since I'm looking forward to purchasing many more publications from StrongFirst and this was the only flaw i could find. Content is absolutely stellar.
