They're not the biggest especially if you go by the number of "PCs sold". In desktop builds maybe they are. Yes I'm well aware that they all get chips from the likes of Micron, Hynix and Samsung including the console manufacturers. But "these big 3" are the suppliers the customers on the PC side are more than "a few" and even those many customers have many product cycles with different order amounts for modules. You've done nothing to show that they are putting in bigger volume orders for a given module from those suppliers. You've just ranted about PC this, PC that.
