I had an iPod 4 (huge mistake BTW!) And it couldn't run any of the best 3D games. This Christmas I got a Nexus 7 (2012) and it runs these games flawlessly. I currently have Injustice, Dead Trigger, Dead Trigger 2, Deer Hunter 2014, Into The Dead, Zombie Highway, Zombie Gunship, And Contract Killer Zombies.

By the way, money isn't an issue since I know how to pirate everything.
