Finally, the Xperia M4 Aqua has reached the U.S. It's now available on Amazon.com, but only the 8GB version is available. We're talking about a mid-range device with a plastic build that features Sony's water and dust resistance. The cost is $349 unlocked, and expandable storage will boost that meager capacity right away.
I'm sure there are better deals out there like the OnePlus One. But waterproof and dustproofing is something. Good for Sony!
