I'd say hardware sales like that are impressive, coming from a software company.
Apple's original core competency was creating hardware, with the software existing to drive hardware sales. (That there is a "hack" in "hackintosh" suggests that this should still be true today. They don't want you to buy their OS and run it on your own hardware, but they're fine with you buying their hardware and running your own OS on it.) Microsoft's core 'competency' has always been software. (I am of course abusing the term 'competency' in this case...)
