I wanted a Windows based tablet and this one came with office and Windows 8. It has been a great disappointment. After a purchase in late September, Windows 8.1 came out in November. I attempted the free upgrade. Following the upgrade the WiFi and bluetooth keyboard quit working. After several attempts to reset the computer guided by Samsung customer service. They brought it in for repair and reverted to Win 8.0. The repair lasted two month. At that time it locked up on a normal Windows update and nothing Samsung online service could do was able to get it to boot. Again, it went to the shop for repair (Samsung). I received it back in January and since the 20th of January to now (3/13) it has failed every auto update. There are over 1000 errors in the Windows log. Every time it went for service and every time Samsung customer support had me reset or refresh the tablet, I lost 4-6 days of productivity. Everything had to be re-installed (Office, Norton 360, all apps) and windows had to go through several normal updates. In total, I have lost use of the computer for 28 days in the 4 month I have owned it. I am now waiting for Samsung to take my call requesting a replacement or refund.
