The Samsung Ativ Tab is a 10.1-inch (26 cm) tablet manufactured by Samsung. The Ativ Tab was announced on August 29, 2012 at IFA 2012, incorporates a dual-core 1.2 GHz Qualcomm Snapdragon S4 processor, and runs the Windows RT operating system. Despite the mixed reception that its Windows RT operating system has received in comparison to Windows 8, the Ativ Tab itself received positive reviews for its lightweight design, its ability to use USB peripherals, and its overall performance for a first generation Windows RT device. While the Ativ Tab was released in December 2012 in the United Kingdom, its release in Germany and the United States was cancelled due to the lukewarm reception and unclear positioning of Windows RT.
