How about the vendor that spends every last dollar trying to make a better product, so they have nothing left over at the end and are barely still solvent? And the product does more and costs less?
Just thinking out loud here.
I think this is a very good point however, I do believe that Apple products are better manufactured (if that makes sense) / materials comparing to a Samsung Galaxy.
I really don't think the R&D costs between the S7 vs S7 was much different if not Apple may have spent more. That's just speculation on how they did the colours esp jet black.
Really and truly, if we think about it. I am sure Apple has made a phone prototype that has all the features the S8 has + more.
When Apple release a product it works. Touch ID worked, Siri worked, Apple Pay worked. Yes they've had a few issues e.g. Apple Maps but they fix without releasing new hardware.
