SIGCIS'ers, I am self-publishing my book about the evolution of mobile/portable computers. Too impatient for the traditional route... A digital version (simple PDF) will be available this Friday night. A "real" Kindle version and a print edition, via Amazon print-on-demand, will follow in the next few weeks. It's a short book about a big story. Mobile/portable computing has roots before the common era, in medieval times, during World War II, and all through recent history. I focused on historical stories, many of which weren't previously told, to explain how we got from then to now. It's not a technical book, reference guide, or coffee-table book. The plain PDF edition is just $8. Kindle will cost a little more, and obviously the print edition will cost more still. I made a little web site to go along with it. That's also where people can order the PDF version. It is http://www.abacustosmartphone.com. If you're curious, then please err on the side of checking it out because I need the money. :) Feedback is very welcome. Please keep in mind that I wrote this for general readers, not historians. thank you, - Evan
