On the iMac front, Kuo indicates that Apple will not be introducing Retina displays to the lineup this year, but that the company is working to fully laminate the current display panel to the cover glass for improved display quality. The process has proven to be challenging, and with lower yields on the 27-inch display than on the 21.5-inch panel, Kuo is modeling for sooner availability of the smaller model. We would naturally expect Apple to introduce both models at the same time, but the 27-inch may see either delayed availability or tight initial supplies as production on the panels ramps up.
