I like it. I used a similar idea for latency, but your example works well for why you need more ram vs a faster CPU etc. Word you are reading = registers; Page your reading = L1 cache; Book open on your desk = L2 cache; Book from library in your house = RAM with more letting you borrow more from the library.; Book in the Library = Disk Space; Books in other Library's you can get with inter library loans = Internet
