Hello Lucas, since I asked this question have reviewed our tablet options and discovered quite a large number of tablets we would have liked to use if x86 were supported. Asus and Acer produce numerous x86 tablets at the moment. The future of Intel Atom for android seems uncertain, but I'm wondering with the advent of Core M if we will see a transition to that for android tablets.
As a side note, there is also libhoudini which allows x86 android devices to use libraries compiled for armv7. I discovered this when I was able to run an ArcGIS Qt app on an x86 android tablet without changing anything. Unfortunately, the process isn't so smooth for the emulator and it looks like I would have to jump through some hoops to set it up.
I just wanted to bump this thread again to let you know that we did consider using ArcGIS Qt in a production environment for X86 android, but are deterred due to the uncertainty of future support for this, lack of built in emulator support, and the potential performance drawbacks of libhoudini.
