Another surprise for me in my iPad learning journey was, clicking the Home button doesn't close your iPad apps. If you are a new iPad or iPad mini user like me, who has no background in using any Mac products including iPod, iMac, or iPhone, and coming from classical Microsoft Windows background then you will also need some time to adjust with iOS interface for a common task. When I bring my first Apple product home, an iPad 4G with WIFI. The first thing I did was to set up my Apple id with credit card details to buy some iPad apps because that's one of the main reasons for buying an iPad.
