The most exciting and compelling phone I've seen so far this year is the Xperia Z2.
I have to agree, it is a very nice looking phone. The build quality looks great, and its incredibly thin and light. In addition, it backs a ton of power and is waterproof. I feel like the Z2 is the Galaxy S5 plus a lot more. If I were interested in a new flagship in the next few months I'd be looking at Sony.
