You don't have to have an Amazon Kindle device to read Kindle books, which is why the free copies of the Kindle version of SAS 9.3 ODS Graphics caught my eye and led me to acquire a copy for myself (albeit through a convoluted route because I live in the UK).
I have the kindle reader software on my PC, my Android tablet, and my Android phone, so I can get myself updated on SAS graphics almost anywhere I like. Amazon's own readers are limited to black and white viewing (except for the new Kindle Fire), whereas my PC and Android devices display the book's contents in colour - handy for a book about graphics.
This Kindle book is free until October 16. Don't hesitate, don't miss out!
