If you've been waiting for the least burdensome tablet you could find, Sony's 17.5 ounce, 6.9mm thick Xperia Tablet Z is now up for pre-order in the US. On top of being the lightest, slimmest 10-inch slate on the market, it's not exactly slumming spec-wise either: there's a 1.5GHz quad-core Snapdragon processor, Android 4.1.2 Jelly Bean, 2GB RAM, an 8.1-megapixel Exmor R camera, NFC, LTE, S-Force virtual surround sound, 32GB storage and a 10.1-inch 1, 920 x 1, 200 display with Mobile BRAVIA Engine 2 tech.
