We are looking to make the switch to a MAC but which one. My wife and I went to the Apple store and saw the iMac and we also looked at the Mac mini. We are still confused between the two. Can anyone share the knowledge on what the real differences are? Does it make a difference to get one with 4 GB of memory? I know I would not buy a computer running a Microsoft OS with only 4 GB of memory. Is the MAC the same? We would appreciate the assistance.
