The comparison is extraordinarily apt.
Apple invests only a small proportion of its profit into R&D. http://appleinsider.com/articles/15/01/28/apples-rd-spending...
Samsung invests more absolutely and more proportionally. http://www.strategyand.pwc.com/global/home/what-we-think/glo...
Of course, much of an iPhone is also made by Samsung. Not sure why creaming off profits is considered a good thing or sustainable . . .
