Just for the sake of argument, Samsung and Micron memory is the same as Hynix? (only memory Dell uses) And GDDR2 video memory found paired with most Dell & HP machines, is the same as GDDR3 which apple uses? In some aspects you are right, Apple does at times focus on form over function, but they DO tend to use better quality/higher end components.
Lenovo uses Samsung memory and they use better SSD drives than Apple, ie a real 128GB SSD vs Apple's not so 128GB SSD. Does one example prove the rule like you're trying to do?
