I was annoyed at the beginning that the tab has repeatedly cut the WLAN connection, always had to be restarted, and it took an eternity with You-Tube videos until they have been launched. was more annoying that has cheated by 2 days before the end of the pre-installed trial subscription of a virus scanner, a virus (dubious). the virus lies be removed only by 8 Neuaufsetzen of Windows. after reinstallation, also of another virus scanner running the WiFi stable and the You-Tube videos start normal quickly. how everything is connected, I can not judge. Otherwise, I think the part quite nice and useful. the display and keyboard can not be faulted ... would be the initial difficulties I had not been given 4 plus an imaginary 1/2 star ... 5's with me never;)
