In 2015 Apple had ~234B in revenue. 10B is only 4.27% of that. If you look at the percentage of R&amp;D vs sales that&#x27;s still actually drastically less than they spent in R&amp;D up until about 2005. It could just be that Apple has decided to spend a bit more percentage wise and they have expanded the amount of things they are researching instead of indicating a focus on one specific thing.
