From Satoshi Nakamoto whitepaper :

Quote

If we suppose blocks are generated every 10 minutes, 80 bytes * 6 * 24 * 365 = 4.2MB per year. With computer systems
typically selling with 2GB of RAM as of 2008, and Moore's Law predicting current growth of
1.2GB per year, storage should not be a problem even if the block headers must be kept in
memory

At BestBuy : "Excuse me sir, i need to get new RAM , I need hmm ... 240GB of RAM please"

And you could get a EC2 instance with 240GB of RAM (with 48TB of HDD space) as of Nov 2012[1], if needed.

You can configure machines like that today with 256GB of RAM (m4.16xlarge for example[2]), less expensively than 4 years go. You can even get a 976GB RAM or 1952GB RAM (with about double that in disk storage) today - an x1.16xlarge or x1.32xlarge EC2 instance. So while 240GB seems like a lot when one is used to using a laptop with 16GB, in reality it isn't out of the ballpark for many needs.

Kind of like 64K seemed like a lot in 1981. Or 1MB seemed like a lot in 1985. etc.
