Sony Xperia Z4 is a skinny mini 10-inch tablet

One of the best Android tablets we've seen all year, the Sony Xperia Z4 is a superslim performance powerhouse.

The Xperia Z4 manages to be even thinner and lighter than last year's model.

Sony packs an optional Bluetooth keyboard with the tablet.

Made of plastic but not fantastic, the Bluetooth keyboard feels cheap and suffers from connectivity issues.

In addition, the small keyboard feels cramped to type on.

When closed shut like a laptop, the Xperia Z4 almost looks like a netbook. Remember those?

Did I mention the Sony Xperia Z4 is a waterproof tablet? Don't go running for the pool just yet -- the extra durability is meant for accidental spills, not swimming season.

A 10-inch tablet with LTE connectivity is rare, especially one with such high-end specs and au courant design.

The beautiful 2K screen on the Sony tablet is one of the best. With a wide color range, colors appear impressively lifelike, whereas HD content looks sharper than real life.

The 8-megapixel rear and 5-megapixel front-facing cameras aren't worth busting out at a party, however the apps in the native camera apps are. The apps, settings and features range from practical to wacky, but they're all fun to explore.
