Have the Asus Tablet with 64 / 500GB are the beginning of December. Even now after 2 months use I'm still very excited. The battery lasts depending on the application 8-10 hours. The charging time via the mini USB port lasts but just as long. My version is very high quality, no semblance of cheap plastic. For me, it is the ideal device, Wifi connection perfect, the Bluetooth connection to my devil plant is cut back to the Preview of the first song immediately. No further connection possible. Hope that someday a driver update comes. Who can live with it, has a super tablet PC in your pocket.
