Where did the PP state that apple gloss over new product models? I saw no such statement nor sentiment.
What I read between the lines was rather a compliment to Apple, namely that the PP speculated the reported R&D sum for Apple in the report might have been too low compared to the other company numbers. If improvement in OSX, IOS etc. are not counted towards the R&D budget for Apple, while the same kind of spending would be at another company (E.g. Windows 8 for Microsoft), then obviously the reported Apple figure would be too low.
However, speculations and specifics aside, the interesting message in the PP's comment, I think, was "Think about what the numbers mean and whether they are comparable or not to the other numbers in the set". Are apples being compares to other apples (no pun intended) or is the report showing a mixed fruit comparison?
