Hi all, I'm looking to purchase my first Mac. I want a notebook that I can take around the house but rarely outside or on battery (other than to train it/keep it from dying). I was wondering if there is a distinct advantage between the two for someone like me who won't be playing games or doing anything media-intensive activities. Here are the two machines I'm considering, same price: http://store.apple.com/us/product/FB467LL/A?mco=Nzk2MTU0Mw http://store.apple.com/us/product/FB990LL/A?mco=Nzk2MTU0Mw I plan on upgrading the HDD/memory myself, of course. Thanks in advance!
