The only annoying feature is the use of wireless mode via Bluetooth in your own 4 walls. Due to the normal wireless network in the apartment, the Bluetooth connection seems to be temporarily disrupted, causing a delay occurs and the gesture is only to see on the screen is delayed. The reconfigure my WLans to another frequency channel could improve this situation, but not completely solve. The small distance between tablet / computer and your wireless modem (usually 1m up to 3 m) might also be an issue - but not to change. On the way (eg the train) I had no problems with the Bluetooth mode. At home I use now the tablet mostly with cable, because it then the desk anyway hardly leaves :)
All in all a good product - other articles for the Bluetooth functionality in the vicinity of WLAN routers would be interesting.
