There is a lot of cheap and cool Android-based devices on the market. But Android Orbiter is not developed yet. Even draft version is not available. But it'd be nice to have it.
I'm considering setting up an MD in a virtual machine on the core, then using VNC viewer on the tablet to connect to it and use the orbiter. I'm not sure how responsive VNC viewer is on the tablet, and there would be some latency, but presumably not as bad as the web orbiter?
If you want remote performance, have a look at x2go
