I've just discovered this great new book iPad Made Simple by Gary Mazo and Martin Trautschold. It explains all the features on your mobile device and reveals time-saving short cuts and hidden gems to help you organise your work and social life, stay in touch with friends on Twitter and Facebook and keep you entertained with photo albums, videos, music, games and much more. Check out publisher site at Apress. Have spotted a few book offers, contact me for more info. as they vary depending where you live.
