Xperia has become my favorite Android phone. Their UI skin is the most attractive of all the android skins, also the most fluid. There is alot of bloatware, but most of it you can delete, the rest you just disable.
Battery life is well above average. The camera takes wonderful pictures (much better than any other phone I have had) Still has microSD expansion. And it's waterproof. All in all, my favorite smartphone so far.
