So beside being thinner, there's actually no advances in them (.1 ghz cpu improvement from the basic top of the line mid 2011 imacs) and you're losing some components that some people still use without having to get an adapter. At least the graphic chip isn't bad an nvidia gtx 660 mx with 1 gig of ddr5. But overall it doesn't look at all like an improvement.. Wooopididoo for being so thin and light that your hyperactive cat can rub against it and it slides off the desk. Better screw it on the desk because if you sneeze it will fly off and splatter on the wall!!
