I currently have a 2 year old MBP and use iPhoto to manage my pictures. I am planning to get a new 21.5" iMac (maybe a 27"). When I bought the MBP the salespeople at the local Apple store said the MPB was better than the then iMac for photo editing and management as it had more power/speed. Is that still the case or would it be better to transfer all my photos to the new iMac since it has a big screen. For what it is worth, I don't need the mobility the MBP provides but I have young children who will be playing games on the iMac (I do back-up regularly). Does the recommendation change if I move to Aperture instead of iPhoto? Thanks in advance.
