Hi all, I'm going to release "version 1.0" of my book in a PDF edition this Friday night. Then in a couple of weeks from now I'll release a Kindle e-book version and a print edition. The PDF version is only $8 and can be ordered right now at the very primitive web site: http://www.abacustosmartphone.com. There's nothing to stop people from sharing or posting the PDF, other than me asking nicely: please do not do that. I am releasing the book early because I need the money. So what's in the book? It is the story of the evolution of mobile/portable computers -- how we got from the abacus to the smartphone. I wrote it in plain English for general and mildly technical readers. There aren't a lot of tech speeds-and-feeds; it doesn't explain how the computers worked or how to program them. It is almost entirely about who made them, why, and how they all improved on each other to incrementally move the ball forward. I think it's interesting. Some parts are very funny. Most of all, it's a story that until never was never told. - Evan
