Tablet for 3D printer controller

I was just thinking about this myself the other day.  I was thinking about how nice it would be to use a Tablet to control a 3D printer/CNC instead of a dedicated PC/RPi/etc etc which would need an external monitor.  Looks like someone else was thinking the same thing.
