There aren't many premium Android tablets worth your money, but Sony has some solid hardware and the software isn't bad either. You don't even have to settle for one of those clunky 10.1-inch monsters. The Z3 Tablet Compact is an 8-inch tablet with great specs, and the price is getting pretty attractive at Amazon ($430 from about $500).
In case you're unaware, the Z3 Tablet Compact has an 8-inch 1920x1200 LCD, 4500mAh battery, Snapdragon 801, and 2GB of RAM. The version on Amazon has 16GB of storage plus a microSD card slot. It's also water and dust resistant.
This device isn't distributed much in North America, so these are international models. However, they're just WiFi tablets, so no compatibility issues. The only difference is you won't get a warranty. There are only a few in stock of each color, but several sellers are listing at the same price. Get on it before they're all gone.
