Do you believe in an iMac with a retina display as soon as 2014? I know many of you customized the iMac and are paying premium price, it is expected that you'd want to keep it for at least two or three years. How many years do you usually keep an iMac before upgrading? Who'd go for the it? Who'd wait a couple of years? Why are you buying an iMac now, and not waiting for the 2014.. 2015 iMac?
