Dealing with EFI issues like this right now! It's made worse because we run Windows 10 IoT Enterprise on the devices and much of the work I did on our 64-bit OS image is mostly invalidated because our next tablet has the exact same processor but only 32-bit EFI.... Oh man, it can really screw with your logistics when you rely on consumer tablets. There's one reason to pay a premium for 'industrial' devices.

I will say this additionally though - the messaging around the Intel Atom line, IMHO has been absolutely terrible. If only our software could run on ARM. I was convinced at one stage they were discontinuing the whole thing and then suddenly they didn't? I don't even know anymore. They have a roadmap so I guess that's something.

TL;DR: Think very carefully before basing a product on consumer-grade hardware, especially with consumer-grade tablets. To the parent commenter, you're probably lucky you DIDN'T push through it :)
