Now that's what wise investment is. Samsung re-invests their profits. In return they get research (order of magnitude more patents than Apple has), manufacturing prowess (semiconductor FABs etc.) and much more. What does Apple have? A lot of hype. Imagine if the next iPhone is not popular (may happen even if it's technically OK - just because people get bored with it), what happens to Apple? What do they have?
That's across "all their affiliates", remember; which could be anything from ships to refrigerators to sewing machines.
But why spend 42B on all that when you already have the tightest, most efficient, most focused R&D in history? Samsung is waiting to see what Apple does next and is spending all this money so they can be ready.
Why spend more, when you can invest a couple of billion in equipment for your contractors' assembly lines -- like buying up all the machines that carve out blocks of aluminium?
Why spend more, when you can buy a cutting edge Israeli company that determines
how flash storage is used and improved in the future?
Why spend more on improving or extending chip fabs when you have already bought a leading company in chip design and custom SOC implementation?
Why spend more to hold onto, maintain or improve plants and manufacturing facilities of your own, when you can quickly get new facilities going anywhere in the world, such as in Brazil?
...and the list goes on.
Why do
all, or
any of these things just to gain control over how things are designed, assembled and used
today (like batteries or applications for glass or metal coatings, for example), when you are already busy reinventing how things are going to be
tomorrow and improving the supply chain that actually gets them into your customers' hands?
The "hype" is that all these Apple competitors have do
something in order to look like they know what they are doing. Samsung is just in a better position to that
something than most others. But have Samsung distinguished themselves as another Sony? Perhaps in quality or reliability, but not in spirit or originality.
By contrast, Apple is most interested in creating products that change the way we do things, or the way certain industries work. All the money in the world doesn't help you do that; but
when you do it, all the money starts flowing to you and you have a chance to keep doing it.
