My parents have been dropping unsubtle hints about wanting an iMac but seeing the price of a brand new 2015 model kept putting them off. I keep seeing the 2011 models for sale now and again which on the second hand market is actually not too bad pricewise but I have some questions. Since it's a 2011 model, is there any danger or any reports of hardware failure because of the age? Would you consider the OSX operating system to be pretty much "parent proof"? They have been using Windows for over 15 years but is it a pretty much easy and simple to use without them ringing up everyday asking how do they do something? Failing to grasp OSX, is installing Windows 7 via Bootcamp a pretty painless experience and it can deliver a familiar experience but housed in an iMac PC?
