I am in the market for a new iMac at this point. I think i'll wait until Mountain Lion comes out to see if they will update the iMac this year. I doubt they would waste time preinstaling old iMacs with Mountain Lion and redoing all current stock if they were going to update it say only a month after ML came out. If ML comes out and the old iMacs are still around, i'll make the jump![]()
If indeed there is a "refresh" model of iMac coming out when ML comes out in July, then the question becomes "Is retina/complete redesign coming in 2013" and whether or not people should wait another year or so.
