Aaron reviews the Sony Xperia Z1, Sony's new flagship Android smartphone. Available at GSMNation, the Xperia Z1 sports a 2.2 GHz quad-core Snapdragon 800 CPU, 5-inch 1080p HD display, 2 GB of RAM, 16 GB of internal storage, 3,000 mAh battery, and Android 4.2 Jelly Bean with Sony's UI. The Xperia Z1 is water and dust-resistant, all while keeping an exterior that measures in at 8.5mm thin. It's an exceptionally powerful phone that works on T-Mobile's LTE in the States (sorry AT&T users, no dice) - but it's costly. Is it worth the extra cash? Part 1 of 2.
