Agree, from my experience any good software for a platform should take as much advantage of the platform as possible. And then work around platform limitations. Any cross-platform apps look non-native, missing subtle platform conventions, and ultimately feeling awkward on such a distinctive platform as iPhone OS. This seems to be a consistent line of Apple's, ultimately aiming to project the "quality" image of the platform, and not diluting the valued brand. This is the same line as John Gruber suggested pondering the purge of overly explicit apps. It did not come down to purging crapware developed natively with Xcode yet, but with thousands of apps in each category, the purgatory moment in one form or the other (e.g. if not purging outright, but subjectively separating into premium and "others" stores) probably is not too far ahead.
