Yes very true; I remember hearing once (I don't know how true this bit is), that Samsung Group alone make up around 20% of the South Korean economy... It may just be me, but I do detect a slight slowing down of Apple's supply chain in recent years though. I know that they've had a lot of trouble when trying to move away from Samsung, simply because Samsung were/are the only single supplier that is able to provide the sheer quantity of components that Apple need. Also, Apple always used to have a habit of having their big product announcements available for order and shipping on the day that they announced them, not 2 months down the line. When you add in potential omissions like the 4k monitors (or any kind of monitor refresh since 2011), you have to start thinking that perhaps they have a few troubles down the line. Whether it's suppliers being difficult, or just a factor of the sheer size that Apple has reached, I really don't know.
