"The hand-holding guide to computers is now updated to show seniors how to use and enjoy the devices sure to be given as gifts, including tablets, e-readers, smart phones, and iPods--and to help them dip into social media and other sites for sharing, including Facebook, Skype, and YouTube. 'Is This Thing On?' is the friendliest, most jargon-free guide to the joy of using a computer. And the missing manual that every senior needs."--Amazon.com.
