This is not a lot of money in the markets where Apple competes.
I guess GT Advanced Technologies might have some scarce expertise.
When I heard the iPhone 5 was going to use a sapphire lens cover I decided to lookup more on the technology and found that GTAT had what looked like the best know-how in its manufacture.
I had also previously seen a story on some tech being created by a company called Twin Creeks that looked pretty cool, and was surprised to see that GTAT had acquired it's assets. That made me think the company was being aggressive in it's pursuit of acquiring/developing cutting-edge manufacturing processes.
Plus, I think solar power is a major part of the future and things will be pretty bleak if it can't deliver long-term, but I like to be an optimist, so why not put my money there?
There is no "scarce" here. GTAT wanted to make and sell a lot of this capacity, they just couldn't get a buyer to risk their capital.
From that standpoint it makes perfect sense for Apple to pony up. They want the end product. There is no need for a third company to take risk, provide capital, and make extra profit. Apple provides the capital, takes the risk.
That's a pretty enormous chuck of change, even for massive corporations such as Samsung.

Apple's move here is a solid move to secure supply of a key material/component for their devices.
Meanwhile Moto has yet to produce a profit, much less meaningful patent protection for Google.
Edit: and that is just the prepayment.

My point is that the companies Apple is competing against don't make these moves because they don't have the financial resources, it's because moves like these don't fit into their overall strategic plans.
If they can make it, so can any other company.
Apple is still enough ahead of the competition in the product development department that they start making these deals long before anyone else.
Plus of course the manufacturers trust Apple to actually take delivery of all and more based on the success of the past.
Being able to put up the money for those kind of prepayments is about the only area in which competitors can match Apple.
Regarding tablets, I'm surprised more Android tablets didn't target the Asus Transformer/Chromebook form factor - seems like an area where Apple wouldn't want to tread (to not cannibalize their Macbook sales).
