Hi all. I am waiting for the new revision of the 24" iMac. I have been waiting since December when I got a $1900 Apple gift card. I have a couple questions. I will be using this for mainly editing recordings from a HD camcorder, Itunes, and burning DVDs, Garageband and such. Is there something I need to upgrade or a minimum amount of something I need for this? Looking forward to the new look of the Imac, really wanting a Blu-ray burner.
