I am very excited to hear your reports from trying this on the 24 inch iMac. I have had my eye on this comp for a while since making the switch about 2 years ago I really don't want to go back to Windows. Is your plan to do all windows on the 24 inch monitor or are you going to try and hook up a second monitor. Why are you going to run vista on the mac? Any and all information would be appreciated thanks.
