Playing infiniti blade on the iPad 2 is so much better than it was on the iPad 1. Imorovements include Much faster start up No lag Extremely responsive (I can now fit 2 moves easily in between attacks which allows you to recover from mistakes) Much better graphics. More shadowing, smoother edges, better colors, more vibrant effects. It really is a night and day difference. The game was very Kathy on my iPad 1. I am happy with the dual core already.
