Ditto. Very nice phone, ics works well. Has better display (higher res, better dpi) than iPhone 5. And most features are better than iPhone 5.
But this thread is old, Xperia S is now being replaced with Xperia T with much improved specs.
The S still seems to be a sweeter handset than the T to me... S still better specs.
The T has larger screen, same resolution but lower ppi and only adds slightly improved CPU+GPU, SD storage +1MP more in its camera.
