yeah, probably.
xperia play has the d-pad and buttons and is probably a good android gaming phone, but iOS has more, better, and cheaper software. Then again, I've seen nice emulators for android. iOS might have them too if you jailbreak or wahtever.
I'm waiting for September, hoping for a new iphone. After several hundred hours, playing mostly tetris and bookworm on my 2005-phone is loosing its luster. I think I have a single 26 hour long game of Tetris going comprised of a few minutes here and there.
