In all seriousness, you raise a good example, and it reflects a very fair assumption: why don't equivalent apps on each OS work equally well? I don't have any experience with that issue (except maybe...Angry Birds?...), so I'm anything but an authority on the question. You're probably right. But give me 10 minutes and I can easily think up 4 or 5 reasons why it's not really a fair comparison, and why evaluating Android and its app ecosystem during its infancy is still too early.
