It turns out quite a bit. I found Gruber's Daring Fireball post pointing out what appears to be Samsung's alteration and reuse of a screenshot image I created in 2008. You see, three years ago I blogged about iPhone apps I thought were a big deal — "game changers." (The post was cross-posted on BlogHer, where it got noticed.) Scroll down to see my excitement then about the ever-useful maps.app, with screenshot in question.
