I agree, I took my jailbroken iPhone to walmart and grabbed one of their demo models and did a side by side to see how much lag there was, everything was pretty much the same, maybe a half a second difference in most apps. The biggest difference was with the photos app, but I have almost a thousand photos synced to my iPhone, I don't know if the number of photos makes a difference or not.
