While this may be the best we get, it just seems odd that that is the case. I mean, I've seen some pretty impressive stuff on my hero, and Angry Birds is not it :P It just seems like a lazy port to me. I've been playing Pandas Vs. Ninjas and it plays flawlessly.
It just seems to me that Rovio could make this much more accessible by reworking the animations, textures, etc. to work on more devices. This is not that complex of a game :P
