Well, first a caveat, it is not about traditional business models, but about tools, techniques etc for marketing and strategy. In fact, probably more than enough to get you through most of an MBA.
And it is extremely well written, with logical flows, explanations, etc, that I find few faults with it.
Unfortunately, the author limited himself to "only" 50 topics, I would have loved to see another 20-25 in there (like Balanced Scorecards, Strategyzers models, etc.), but you can't have everything you want and the topics covered are very well thought through.
