The Kindle edition which is available on PC, Mac, iPhone, iPad, iPod Touch, Android, and Windows Phone 7 as well as Kindle devices will be absolutely free on Tax Day tomorrow, Tuesday, April 17, 2012 PDT. Please let your family, friends, and coworkers know about this one day offer. Thousands of people downloaded the Kindle edition during the Presidents' Day promotion, and I am hoping even more people will be able to download a free copy tomorrow.
