The tide is slowly turning. These days, games launch simultaneously on both platforms much more often than before, and we're getting pretty good Tegra exclusives too.
Imo, piracy works on Android and iOS too, so that a moot point. Fragmentation though is a valid point. If EA and Gameloft have trouble optimizing their games, what about small indie devs made up of 2/3 people?
PS: Btw, nice insight FreakZone. Thanks!
