As someone who's just moving from an iPhone 3G, I know all about the pain of stuff not working well, or not working at all, on lower end hardware.

If Rovio had said that it didn't work on each of those devices for a different reason then that would be a good example of the android fragmentation bogeyman. Since they're all just lower specced devices, presumably struggling for basically same reason, it's not really a great example.

Regarding iAds, I've seen a few folk claiming they're game changers, but my point was that Apple are jumping heavily into the free/ad supported arena which reduces the impact of any contrast with Android on that point.
