I asked why the MacBook Pro Retina have soldered RAM. Some replied that having soldered RAM allow the MacBook Pro Retina to be thinner, never mind that there are laptops as thin as the MacBook Pro Retina that have upgradable RAM. I am letting this one slide it now. So, why does the 21.5-inch iMac have soldered RAM? Also, why does the Mac mini have soldered RAM? I can't help but to reason that this was done so that Apple can charge exorbitant upgrade prices at the time of purchase. After all, Scrooge McDuck ...I mean Tim Cook... needs more money so that he can build another solid gold swimming pool.
