I ordered the tablet that I will be using to control the test rig today. It is the Chuwi 12" dual boot (Win10 and Android 5.1) Here is the link: http://www.banggood.com/Chuwi-Hi12-Intel-Z8300-Quad-Core-1_84GHz-12-Inch-Dual-Boot-Tablet-p-1044181.html . I think it will be a great interface, the touchscreen is a good size for people like me who have fat fingers and poor eyesight 
It is on sale right now with a $36.00 USD off coupon on the banggood site. This makes it $225.06 USD delivered to your door, which I think is a fantastic deal for this tablet.
