As more new's about the Playstation 4 reveals itself, some people forget the other products being developed by Sony, one such is the Android Handset Sony Xperia Z.
"The phone is waterproof and dust proof — so, not surprisingly, it feels solid and high-quality in your hand. There’s no cheap plastic here, so common on other Android handsets"
"The Xperia Z felt fast while bouncing around Android’s interface and switching between apps. You can thank its 1.5 gigahertz Snapdragon S4 Pro processor and 2 GB of RAM for that. It’s not the only speedy Android phone around, but it’s certainly one of the most refined. LG's Nexus 4, for example, also sports a glass rear, but it feels incredibly cheap and garish compared to the Xperia Z. At this point, I hope that Google ends up tapping Sony for its future Nexus phone. (No, I’ll never get over the cheesy semi-holographic design on the rear of the Nexus 4)"
"Pricing and availability for the Xperia Z hasn’t been announced yet. Sony also introduced the Xperia ZL this week, a slightly thicker (but also smaller) phone without the dust and water resistant case"
