Sorry if this has been posted, I don't think it has. My wife (I love her) suggested that I keep my 1.83 Ghz CD iMac and use it as an external monitor for the new 2011 iMac. This all came up b/c I said I was going to buy one and sell the older iMac. Question is, is this easily done? Is the connection stable? What kind of cable will I need? Thanks guys!
