As likely as this seems...what are the arguments for and against? I am returning to the states late September and would like an iMac waiting at the house for my return. If there is not an update yet I will be tempted to wait but I am really hoping to see an update before then. Opinions? If not by then, then when? I personally only ask for core duo 2 and better video card. More options would be great of course. I am very confident the wireless keyboard and mighty mouse upgrade will be there.
