Maybe it is a silly question. Still I would like to get an answer. The only component of a nMP that every user can change without special technical skills and without risking his Apple coverage...is RAM! It is also the only important part of a nMP separately available. No matter if you buy a nMP in the USA, Europe or elsewhere, a simple calculation will show that Apple charges about twice the market price for RAM. With the price of 32GB "Apple" RAM you can buy about 64 GB RAM made by known manufacturers like Samsung, Kingston or other makers. The same applies to 16 GB "Apple" RAM compared with 32GB RAM of other sources. The minimum amount you MUST buy with a nMP is 3x4GB=12GB. Apple does not deliver the nMP with no RAM at all. Now, I do not understand the reasons why people order more than those unavoidable 12GB Apple RAM with any nMP, instead of adding RAM by themselves. I know that the 1 year standard coverage or the 3 years Apple Care coverage will not apply to any RAM bought and installed by a buyer of a nMP. Besides that, and since known manufacturers' RAM will work as well as already installed Apple RAM (Apple does not manufacture their RAM) I would conclude that if some buyers or some companies might not care at all at saving any money, all other rational and budget thinking buyers of a nMP should just order those unavoidable 12GB, try to resell them (even if they won't get much), and then buy by themselves either 32 or 64 GB of any brand of RAM with a solid reputation. Proportionally 64GB will mean a smaller loss than 34GB because of the difference between the amount Apple included in the price of the nMP for RAM as compared to the small amount of reselling those 12GB. That is the unavoidable loss. In the case of buying 16 GB with a nMP the theoretical saving will be so small that it won't be worth while because of the above mentioned unavoidable loss. But with 32GB and specially with 64GB, one can get about twice as much RAM if bought by oneself compared to what one gets from Apple. I would like to know if besides the love to Apple, which I certainly share, and besides the non coverage by Apple of separately bought RAM, there might be another reason I do not know or understand to buy more than just 3x4 GB with any order of a nMP and then add by oneself the quantity of RAM one needs. Thank you in advance for explaining to me what I do not understand by myself.
