Steve Blank is shooting himself in the foot, I think.<p>He's said (repeatedly?) that he won't make ebooks versions of his books because he wants people to be able to write in them, and to highlight things.<p>I have around 800[1] books in iBooks. I own, literally, zero, physical books. (I live nomadically and all my possessions fit in a single bag.) I don't care how great the book is-- and frankly, this book is at the top of my "want to buy list", and prior to it, the 4 steps to the epiphany was at the top of that list for FOUR YEARS.<p>But his reasoning is mistaken-- these features aren't unique to physical books, in fact, they exist and even work much better in e-readers.<p>iBooks allows you to write notes about what you're reading, and highlight things for future reference. In iBooks your notes and highlighted text along with bookmarks also sync across devices, allowing you to read it on the iPad at night and then pick up on the iPhone at work. ( I don't know if the kindle reader has similar features. )<p>Here's the thing, this is the customer development guy who says "Get out of the building." Yet he's not listening to his own customers! His customers are <i>demanding</i> ebook versions, very emphatically, and they do so on every single blog post he makes mentioning either book, he gets dozens and dozens of comments from people asking when there will be an iBooks or kindle version.<p>For me, his refusal to listen to his own customers kinda goes against his entire business agenda. (I think this issue is just hitting a personal blind spot of his, and I'd have to guess that he's afraid the books will be pirated if he releases them electronically. I'm not saying he's a hypocrite, but he, of all people, should be listening to his customers.)<p>[1] Couldn't believe this myself, so I just checked. iTunes reports 794 items. I think about %10 are ephemera (like maps in PDF format, etc). Maybe %20 are newsletters I've subscribed to over the years that are in PDF format. But its shocking how quickly ePub is being adopted as a standard. I've probably actually bought less than 100 items from the iBookstore.
