I've been using windows based PC's since 1994 and after Microsofts latest version(win8/8.1) it was time to call it a day. I have had my iMac for a while now, with not ONE issue, i only wish i had made the switch a long time ago. I know this kit does not come cheap but believe me its well worth the extra cash. The after sale service you get from Apple is second to none not that i have needed to call them, but what i have heard from friends and family they are in a class of their own. The only worry i had about making the switch was getting familiar with the OS(Mavericks), after a couple of weeks i have now become very confidant with its interface. I seriously suggest you make the switch you won't regret it.
