Apple should charge far less. Certainly, less than Amazon, because you are not buying just one SSD stick as with Amazon, but a full computer. Now, add to that the extra RAM price and the extra whatever else (including cables, adapters, etc), and you end up paying twice or more for the computer. In other words, Apple could slash the prices of all their devices to half and still make huge profits, significantly expanding global market share. But they do not get it.
