I played on it and while it was playable and very easy to play on the mini (light weight), I turned on my iPad 4 and the game SCREAMS. I love my mini so much but the 4 definitely is the superior one for high end games. I think the ultimate iPad is coming next year in the form of an all new 5 at under 1 lb.
Oh, I bet! I'd love to see how the new Modern Combat game runs on the iPad 4. Must be sick!
