Samsung on Thursday announced the ATIV Tab 3 at a press event in London. The company emphasized that the tablet was running Windows 8 and not the oft-criticized Windows RT operating system. The slate, which carries the distinction of being “the world’s thinnest Windows 8 tablet,” is equipped with a 10.1-inch 1366 x 768-pixel display, an Intel ATOM Z2760 processor, 2GB of RAM and 64GB of internal storage. The Tab 3 also supports the company’s S Pen stylus, which is built directly into the device. The tablet feels fantastic in hand, although it features Samsung’s traditional plastic casing, and is very similar to the Android-powered Galaxy Tab. Samsung has bundled a keyboard stand and Office 2013 with the device. The company is also promising up to 10 hours of battery life. The ATIV Tab 3 will arrive in stores in early August for a pricy $699.
