Thanks again everyone who posted. For the sake of closure, I thought you might like to know that I ended up getting the 15inch i7 AG and I couldn't be more happy! I still lust over a big screen and will probably pick one up in the fall sales. At the moment I'm leaning towards the newly released hp zr24w, although a lot can change between now and then. But in the mean time I'm more than satisfied and just enjoying my new mac!
