Could be. I think it's more that iOS has had a relatively consistent UI style since day 1, while Android's style has been changed more. Additionally, most Android apps have traditionally come after their equivalent iOS apps, and so have often been the victim of bad UI ports (as evidenced by the large number of Android apps that look distinctly iOS-esque).

I wonder if Window Phone will suffer from the same as it (hopefully) becomes popular. I assume the vastly different UI style will probably prevent some of this, though.

Android's UI history is about as checkered as you can get. It's only just stabilizing with the last major rev.
