I'm about to pull the trigger on a new iMAC mine from 2007 is starting to give me some issues. However I was talking with a developer recently and he mentioned there were calls or coding that referenced a refresh for the iMAC in 2011. Now I don't want to get burned after paying 3K for a system so does anyone here have any credible information or speculation on this?? I know apple keeps quiet, but should I wait!??
