1) it is a pretty big book;
2) So far, its text has been easier to read than "the 4 steps to epiphany";
3) IMO, its "killer feature" is NOT that it integrates Business Model Canvas content into Customer Development Model, but that it discusses and exemplifies the application of the Customer Development Model to offline businesses as well as online ones.
Eric's book seemed more like marketing material for lean targeted at big cos who have no idea what it is.
Start Small Stay Small was very close, but it did not espouse much Customer Development.
As you point out, it's not Eric Ries book. I suspect it's not Steve Blank's Manual, as it's more of a reference. Maybe the Manual has a brief overview as well ? I mean, to use it as a reference, you first need to understand the method and what to look out for.
Specifically for customer development, I'd check out The Entrepreneur's Guide to Customer Development: A cheat sheet to The Four Steps to the Epiphany.
And compare it to the author you're talkin about http://www.ashmaurya.com/about/ that clearly states in his page "In late 2009, I ran into into Steve Blank’s lectures on “Customer Development” from where I followed the trail to Eric Ries’ early ideas of the Lean Startup."
A perfect example of why it's good to quote what you're replying to. Your message was so far over to the left, and was pushed down far enough below the actual post you were replying to, that the context got lost. Scrolling down the HN page, your reply appeared to be a reply to the parent post, implying you were calling Steve's book a ripoff.
The seminal work from which Ash's book (and mine) sprung was The Four Steps to the Epiphany, published in 2005.
I'm just not very read-up on their backgrounds, but which companies have they started and successfully built? Anyone know?
Are they currently working on any big idea now? I think it would be really interesting to see them try to apply their own theories into practice.

They are both the real deal - especially Steve Blank, who did multiple companies.
I do think is Steve Blank is more legit, but not because he did multiple companies - if you worked on several venture-backed companies throughout your life but they all went nowhere, you must suck as an entrepreneur. I just looked up Epiphany and this answers my question, he founded it, did $71.5M in revenue, and it IPO'd, so Blank definitely knows what he's talking about: http://en.wikipedia.org/wiki/Epiphany,_Inc.
IMVU on the other thand had good traction and Eric Ries was VP of Engineering there, but what's happened to it since? Just looking it up on crunchbase: http://www.crunchbase.com/company/imvu - no big exit/big numbers or anything special like Epiphany?
And here's his LinkedIn profile: http://www.linkedin.com/in/eries - it just doesn't show any blockbuster results as an entrepreneur, just a lot of advising/marketing/blogging.
