Why not get the Sony Xperia Play?
Xperia Play ... hmm it's really nice smartphone, with gamepad but i saw Galaxy S 2 in action and I want something with s. amoled. Galaxy Note is perfect for me. Huge display 5,3" , s.amoled -> vivid colors, great contrast, perfect black color, resolution 1280 x 800 pixels, 2 x 1,4 GHz CPU with mali 400 MP graphic (I hope that enough for constant 50/60 fps with open GL). Physical gamepad is very good, but for me overall quality is much more important. I play games like: vagrant story, final fantasy 8,9 , chrono cross and onscreen gamepad is fine for games like those.
The best for me -> Galaxy s 2/note with gamepad
