My wife purchased a Rocket ebook for me for Christmas. She started here at Amazon. She carefully checked the Rocket web site as well, and spoke to the folks that make the Rocket. She was assured that everything required to use the Rocket with a Mac was included. Wrong! Any Mac currently being made or made during the past year or so requires a Keyspan connector between the e-book and the Mac USB slot. This costs $80. It is not mentioned in any documentation that comes with the ebook. It took me more than an hour to get through to the company. At first they responded by saying it was at their Website and/or in the FAQ section, but we "went to their Web site together" while I was on the phone, and they reluctantly conceded that they had mislead the public. The company does literature. Guide provided on the ebook. Regardless of how much I may eventually enjoy this toy, I'll never develop a high regard for NuvoMedia, which makes the Rocket ebook.
