I have the update on my 360. It's nice. I have installed 2 games on the hdd, but I want to upgrade to the 120 so I can put like 12-13 games on the hdd if needed. I will mainly just put games on there that I will play a lot of for long periods of time. I beat fallout 3 but if I were to play it again or a game similar I would put it on the hdd.
