Free Android eBook

I've just published a free ebook "Android: What it is and how to use it". It explains not just how to use your Android smartphone or tablet, but what Android is and the roles played by the different parts of the Android desktop. It is aimed particularly at retired people who might be struggling with their Android device, so if you have any of these in your family you might like to pass it on to them. The book can downloaded from www.smashwords.com/books/view/1063175.
