I just noticed that what looks like the final pdf/epub/mobi version of MacRuby book is now available to people who already bought the book or for new customers. If you already bought the book, get your update from: https://members.oreilly.com/account/emedia/index Otherwise the book is for sale on O'Reilly's site: http://shop.oreilly.com/product/0636920000723.do and Amazon: http://www.amazon.com/gp/product/1449380379/ref=as_li_ss_tl?ie=UTF8&tag=merb... The print version will probably be available very very soon now. Sorry for the wait and please, try to leave an Amazon review. Thanks, - Matt
