Targeting multiple OS

So I’m thinking of developing a game for Android and iOS and I’m looking for a game engine that can target both. It says that Unity can do this but how easy is it really? Will it just magically work or is it a lot of OS specific stuff to work with?

It is fantastically easy. Unity v3.4 will ship early July '11 and will have a demo project that can run on all the platforms we support. Note that to target iOS and Android you’ll need to purchase at least our iOS and Android Basic products ($400 each).
