Nice artical! However the supposed rationale for having ACPI WMI is wrong, the real reason is that it allows firmware to (almost) directly expose higher level WMI objects, which is in my opinion clearer and easier to use than the sysfs style used in linux. The problem is that it stopes making any sense when all the supporting infrastructure is not available.
