Looking forward to when this comes out on either the itunes bookstore or Google store. I find dead tree format books to be a hideous waste of natural resources.
The first C= of his book came out not too long ago in iTunes and is a terrific read.
There's a lot to be said of physical ownership versus revokable and otherwise volatile digital copies. Yes, I realize physical ownership is volatile in terms of fire, frost, and frippery, but at least not volatile in terms of device upgrades or whims of the provider: I have never moved into a new house and not been able to keep my incompatible books, and I've never had a publisher show up at my door to take back a book because they no longer are interested in its publication or distribution, or because it suddenly violates their every-changing terms of service.
Besides, just think of all the carbon being sequestered in the "dead tree format." With trees being renewable, the more we print, the more we save the planet!!
