Use any old droid ware (Phone, tablet, settopbox mediaplayer thingy) as controller.
(Once the firmware will allow this)
In a way this is a nice option to use old ‘gadgets’ for something more usefull.
Also it would be cool to see GroundGontrol on droid.
old phones and tablets are better suited for dusty environments then laptops or other PC’s that consume lots of air to cool the cpu.
