Technically speaking, Sony's newly unveiled Xperia Tablet Z is ever-so-slightly skinnier than Apple's iPad mini, measuring a scant 6.9 millimeters thin versus 7.2 millimeters. The difference in depth isn't exactly splitting hairs, which is measured in micrometers, but for all intents and purposes, the two tablets are comparable in thickness, or lack thereof. Unlike the iPad, however, Sony's tablet isn't afraid of a little water.
Based on information contained in a translated press release from Sony Mobile Japan, the Xperia Tablet Z is both waterproof and dustproof, so if you drop it while sitting poolside, it's not the end of the world (or the tablet).
It's also lightweight at 495 grams, though if still comparing to the iPad mini, Apple's device would win this round at 308 grams (Wi-Fi) to 312 grams (Wi-Fi + Cellular). Despite our weight and thickness comparisons, these two slates aren't competing in the same category. The iPad mini is a 7.9-inch tablet and the Xperia Tablet Z is 10.1 inches (1920x1080).
On the hardware side, Sony's tablet features a 1.5GHz quad-core processor, 2GB of RAM, 32GB of built-in storage, and 8.1MP camera. It also has NFC support and runs Android 4.1 Jelly Bean.
No word yet on price or when Sony plans to launch this tablet elsewhere in the world.
