We might have gotten the last copy.
As you can see from the links to both Business Model Generation: A Handbook for Visionaries, Game Changers, and Challengers (deluxe version) and Business Model Generation: A Handbook for Visionaries, Game Changers, and Challengers (portable version), neither version is now available directly from Amazon.com.
We learned of Business Model Generation from Mr. Handshake 2.0 who learned of it from Business Models Illustrated in the April 2010 issue of Entrepreneur. The Business Model Generation site has a pretty cool "page turning" .pdf demo of the book, but we nationalized Mr. Handshake 2.0's deluxe copy until our own portable start-up version arrived, which we announced on Twitter via TwitPic:
Given that Handshake 2.0 was selected to pitch its business concept at the VT KnowledgeWorks Entrepreneurship Summit on April 7, 2010, we, ahem, thought a refresher course in business models might be in order.
While we're studying, you're welcome to watch this cool time lapse video from the book cover's designer on how it came into being.
