I am looking for an Android tablet which can be mounted by Ubuntu to transfer files. At this time I do not want to install Ubuntu on the tablet. Since Android 4.x there are problems preventing Ubuntu to copy files from and to mobile devices. I am looking for a tablet which does not require any proprietary software to be connected to a computer. This is very hard to figure out from the hardware manufacturer's information. In most cases I would need to order the tablet and try it myself. I hope there is someone out there having found a nice tablet (10", WiFi, 3G) that works smoothly with Ubuntu 12.04.
