No PC, not even a laptop? Concerning computers, you actually don't need a powerful PC to run this game. As for a mobile version, I don't think something like that is on the radar right now (if at all). However, I don't think its a question of compatibility, but more of, will it even run on a tablet?
As awesome as a mobile version of the game would be, the slow CPU's in tablets would probably fry if it tried to run any intense simulations. Hey, who knows... maybe we'll see it in the future.
We can always be optimistic.
