The iPad Air is a trully amazing device. It lives closeby to me, within reach, because I use it so often. Unlike the desktop and the laptop which we power off when stop using them, the iPad is always powered on. When finish using the iPad you just close it up like a book. When you want to use it you just open it up and it is there instantly to use.
What do I use it for?
Web browsing, it has Apple's Safari and Google's Chrome web browsers installed. Wikipedia, News, almost everything you want to know that is on the WEB. (Thankyou Sir Timothy John "Tim" Berners-Lee, OM, KBE, FRS, FREng, FRSA, DFBCS (born 8 June 1955).
Electronic mail. I still have a University of Newcastle email address roger.broughton@ncl.ac.uk (14.7.2015), and a login id to the university computing services namely nroger, that is Roger at Newcastle University.
Photos, videos.
Facetime. Skype. Connections via Wi-Fi to house Broadband in house and garden, Bluetooth to devices closeby in-room, Cellular mobile connectivity almost everywhere.
