Recently I bought an Android tablet, the 7" Yuandao N70HD. The tablet runs Jelly Bean, and comes "almost-rooted", meaning root is readily accessible, but not fully enabled. Searching the web reveals the existence of Windows EXEs and DOS batch files that enable full root access on the device. Inspecting one of these batch files shows that it simply copies certain native executables from the Android SDK to the device.

Now, perhaps root is not necessary to run CogDroid. :-) Anyhow, here's a screenshot of the tablet showing CogDroid running the image that powers this website. VNC access into the image works too.
