Guys, even I am contemplating buying Xperia U. Very confused between U, Sola and Neo V. Even Neo V has all the features of U minus dual core. Does this make difference in real world and not the synthetic benchmarks? Also, Neo V has expandable storage! Rest all the specs are same, I believe, for U and Neo V. So how is Neo V as alternative to U and Sola? And what are the drawbacks for U apart from memory (not a concern as I have a dedicated music player and tablet for gaming!!)
