Printer drivers seem fine. Scanner drivers seem fine. USB mouses and keyboards work fine. Most Apple products can't really be expanded in many other ways.
I'd say the hardware support is fine for what little customisability Apple allows on the hardware that they sell. Perhaps the Mac Pro might have some issues with internal cards (I honestly wouldn't know ...), but those devices are not affordable for 99% of the people.
