The IFA show currently on in Berlin <https://www.theregister.co.uk/2019/09/10/windows_on_arm_intel/> has a couple of exhibitors showing off devices running Windows-on-ARM. (Or, more accurately, Windows-on-specific-Qualcomm-ARM-chipsets-only.) While they offer good battery life, they are expensive, and have compatibility issues (no emulation for 64-bit Windows x86 executables, only 32-bit ones). And Intel clearly doesn’t like them.
