For what it's worth, I tried to "play"the first turn on my iPad. It never makes it to the dashboard or map. It spins for a while acting like something is going on and then stops.
I actually would like it to run successfully on an iPad and there is no reason we can't succeed at that. All the technology we are using is cross platform. We just don't have one here yet to test on. We'll do some specific testing on different platforms as we get further along. I think the iPad should be a perfect place to play planets.
