Scroll Down Books, the newest Macintosh ebook publisher, today announced its first two titles. In “Buying Used Macs,” Neale Monks walks users though the process of spending their money wisely when used Macs. He offers the background on the different Mac models and points out the good and bad points of each model and whether it’s a good idea to buy, upgrade or not even bother. Chris Siebold’s “iMovie – On the Cheap” will take users through the process of becoming a movie mogul; quickly, painlessly and cheaply. Questions on lighting, recording, editing and even location shoots will quickly be answered in this edition. Both ebooks are priced at US$5.
