I was hoping Chris Pruett would post a version of his talk, "Fact and Fiction: Lessons From Wind−Up Knight and Rise Of The Blobs" but he has not done so yet. The talk is available on the GDC Vault so if you attended GDC you can watch it there. It's only 23 minutes.
In it he attempted to break some common myths about iOS vs Android games. Of course this is just his experience but he made the point that most of the myths of iOS vs Android are not backed up by any data so he brought all his data.
I'm kind of hoping if I post this he'll feel compelled to post a version of his talk in his own words instead of mine. Hey Chris. Post your talk! In the meantime here's my summary of his talk
