So while Apple can have an occasional surge, there are multiple opportunities for Android surges feed from multiple sources.
The other side of the coin, however, is that Android's market share is split across multiple manufacturers, so it's difficult to judge how well any particular one of them is doing relative to Apple (who, of course, have their market share all to themselves). I imagine Samsung are the largest manufacturer of Android Smartphones (?); it would be interesting to see how they are doing compared to Apple.
