I wish Apple would spend some more R&amp;D money fixing up their Mac application-level software, which in my opinion has been on a gradual decline since about 2005.<p>More seriously though, Apple’s revenue is much higher than these companies, and their R&amp;D budget is still in the same order of magnitude (larger than Qualcomm or Facebook, about the same size as Google). So the answer here seems to be that they have a more efficient business model or participate in larger markets than Facebook or Qualcomm or Google.
