I seriously hope apple adds mdp-in to whatever the new size imacs ends up being, not just the biggest. I have a 24" now and wouldn love to go down to a 21.5 but I dont want to upgrade and not have video in for my MBP. I've used the 27" many times and it just wouldn't fit into my house right. So what are the odds? Will apple make this feature an exclusive of the big iMac?
